These Terms of Purchase (“Terms”) apply to purchases made through heyuseful.com (the “Website”).
By placing an order through the Website, you acknowledge that you have read and agree to these Terms, together with any other policies that apply to your purchase, including our Shipping Policy and Return and Refund Policy.
1. Eligibility to Purchase
You must have the legal capacity to enter into a binding agreement under the laws applicable to you in order to make a purchase through our Website.
If you place an order on behalf of another individual, business, or organization, you represent that you have the authority to make the purchase on their behalf.
You are responsible for providing accurate, complete, and current billing, payment, contact, and delivery information when placing an order.
2. Products and Product Information
Heyuseful offers cycling accessories and related products designed for everyday riding, including bike-mounted accessories, cycling storage and carrying solutions, rider comfort accessories, maintenance and roadside tools, and other practical cycling essentials.
We make reasonable efforts to ensure that product descriptions, photographs, specifications, dimensions, colors, quantities, compatibility information, prices, and other product information displayed on our Website are accurate.
However, minor variations may occur because of:
- Photography and lighting;
- Screen and display settings;
- Measurement methods;
- Manufacturing tolerances;
- Packaging updates; or
- Reasonable product improvements.
Product images are provided for general reference. Unless expressly stated otherwise, accessories, bicycles, tools, clothing, plants, scenery, or other props shown in lifestyle photographs are not included with the purchased product.
Customers are responsible for reviewing the relevant product information before placing an order.
For cycling accessories that depend on dimensions, mounting locations, handlebar configuration, valve type, bicycle component compatibility, or other fit requirements, please review the specifications carefully before purchasing.
3. Prices and Currency
Product prices are displayed on the Website and confirmed during checkout.
The price applicable to your order will generally be the price displayed at the time the order is submitted.
We may change product prices from time to time without prior notice. Price changes will not normally affect orders already accepted, except where an obvious pricing, technical, or processing error needs to be corrected as permitted by applicable law.
Promotional pricing, coupon codes, discounts, bundles, and other offers may be subject to additional conditions.
If your payment account uses a currency different from the currency displayed at checkout, your bank, card issuer, or payment provider may perform currency conversion and may charge additional conversion or transaction fees.
Any such fees charged independently by your financial institution or payment provider are outside our control.
4. Order Placement and Acceptance
When you submit an order through the Website, you are making an offer to purchase the selected products.
After an order is submitted, you may receive an automated order-confirmation email acknowledging that we have received your order.
An automated order confirmation does not necessarily mean that the order has been accepted, processed, or shipped.
We reserve the right, where reasonably necessary and permitted by applicable law, to review, reject, limit, or cancel an order because of circumstances including:
- Product unavailability;
- Incorrect product information;
- Obvious pricing errors;
- Invalid or incomplete shipping information;
- Invalid or incomplete billing information;
- Payment authorization failure;
- Suspected fraudulent or unauthorized transactions;
- Duplicate orders;
- Unusually large quantities;
- Technical or system errors; or
- Legal or regulatory restrictions.
If we cancel an order after payment has already been collected, the applicable amount will be refunded to the original payment method.
5. Payment Methods
Available payment methods will be displayed during checkout.
Payment options may vary depending on the customer's location, device, checkout configuration, and the payment services available at the time of purchase.
By submitting payment information, you represent that:
- You are authorized to use the selected payment method;
- The information you provide is accurate and complete;
- You authorize the applicable payment provider to process the amount displayed at checkout; and
- You agree to pay the total amount presented before completing your order.
Payments may be processed by third-party payment service providers using their own payment-processing and security systems.
6. Payment Authorization
Orders may be subject to payment authorization, verification, fraud screening, or other security checks performed by Heyuseful, the payment provider, the card issuer, or the applicable financial institution.
Payment may be declined or delayed because of circumstances including:
- Insufficient funds;
- Incorrect payment information;
- Incorrect billing information;
- Card restrictions;
- Security controls;
- Payment-provider requirements; or
- Authorization failure.
If your payment is declined, you may need to contact your bank, card issuer, or payment provider directly.
We are not responsible for fees independently charged by your bank, card issuer, or payment provider.
7. Shipping Destinations
Heyuseful currently ships eligible orders to the following destinations:
- United States
- Canada
- United Kingdom
- Australia
Shipping availability may depend on the product, delivery address, carrier availability, and applicable shipping restrictions.
Customers are responsible for providing a complete, accurate, and serviceable shipping address.
We are not responsible for delays or failed deliveries resulting from incorrect or incomplete information provided by the customer, except where otherwise required by applicable law.
Please review our Shipping Policy for additional information.
8. Shipping Fees and Free Shipping
A flat shipping fee of US$2.99 applies to orders with a discounted merchandise subtotal of US$29.97 or less.
Orders with a discounted merchandise subtotal over US$29.97 qualify for free standard shipping.
For purposes of determining free-shipping eligibility, the qualifying merchandise subtotal is calculated:
After applicable discounts and before taxes, duties, customs charges, or other government-imposed charges.
For clarity:
- US$29.97 or less: US$2.99 standard shipping;
- Over US$29.97: Free standard shipping.
Any applicable shipping charge will be displayed during checkout before the order is completed.
9. Taxes, Duties and Import Charges
Depending on the destination, an order may be subject to sales tax, VAT, customs duties, import taxes, brokerage charges, or other government-imposed fees.
Where Heyuseful is legally required to collect applicable taxes or similar charges, they will be collected or presented as required by applicable law.
Where customs duties, import taxes, or other charges are assessed separately by customs authorities, carriers, or other authorities, responsibility for those charges will be determined in accordance with applicable law and our Shipping Policy.
Customs procedures may also affect delivery times.
10. Order Processing and Delivery
Orders are generally processed within 1–2 business days.
After an order has been processed and dispatched, the estimated transit time is generally 7–15 business days.
Business days generally exclude Saturdays, Sundays, and applicable public holidays.
Therefore, the overall time between placing an order and receiving it may include both:
Order Processing: 1–2 business days
Estimated Transit Time: 7–15 business days
Delivery estimates are provided for general guidance and are not guaranteed delivery dates unless we expressly state otherwise.
Delivery may be affected by circumstances including:
- Carrier delays;
- Customs processing;
- Severe weather;
- Public holidays;
- Transportation disruptions;
- Incorrect or incomplete delivery information;
- Unusually high order volumes;
- Government restrictions;

- Other circumstances outside our reasonable control.
Tracking information will be provided when available.
11. Order Changes and Cancellations
If you need to change or cancel an order, please contact us as soon as possible:
Email: service@heyuseful.com
We will make reasonable efforts to accommodate a change or cancellation request before the order has progressed too far through processing or fulfillment.
However, we cannot guarantee that an order can be changed or cancelled once processing or shipment has begun.
If an order has already shipped, an eligible product may instead be returned in accordance with our Return and Refund Policy.
If we successfully cancel an order for which payment has already been collected, the applicable refund will generally be returned to the original payment method.
12. Voluntary Returns
For eligible products, customers may request a voluntary return within 30 days after delivery.
The 30-day period begins on the date the applicable order is delivered.
To request a return, please contact:
before sending the product back.
Returned products must satisfy the eligibility and condition requirements described in our Return and Refund Policy.
Depending on the product and circumstances, return eligibility may require that the product be returned in appropriate condition together with applicable accessories, components, manuals, and packaging.
Our customer-support team will review the request and, where applicable, provide return instructions and the appropriate return destination.
Do not send returned products to the company address listed in these Terms unless our customer-support team specifically instructs you to do so.
The authorized return destination may be different from our company address.
Nothing in this voluntary 30-day return policy limits mandatory cancellation, withdrawal, return, warranty, conformity, or other consumer rights that may apply under applicable law.
13. Refunds
Once an eligible returned product has been received and reviewed, we will process the applicable refund in accordance with our Return and Refund Policy.
Approved refunds will generally be issued to the original payment method unless another method is required or agreed upon as permitted by applicable law.
The time required for a refund to appear in your account may depend on your bank, card issuer, payment provider, and applicable payment-processing network.
Heyuseful does not control processing times imposed by third-party financial institutions after a refund has been issued.
Refund treatment of original shipping charges and other applicable costs will depend on the reason for the return and the requirements of our Return and Refund Policy and applicable law.
14. Damaged, Defective, Incorrect or Missing Items

- Damaged;

For an eligible voluntary return based on change of mind, personal preference, or another reason not attributable to Heyuseful, the customer is responsible for applicable return-shipping costs unless otherwise stated by us or required by applicable law.
Where a return results from a damaged, defective, incorrect, or otherwise non-conforming product attributable to Heyuseful, we will be responsible for reasonable return-shipping costs where a physical return is required.

Our customer-support team will provide the applicable return instructions and return destination after reviewing the request.
The company address listed in these Terms is not automatically the return address.
Unauthorized returns sent to an incorrect address may result in delays in processing.
Nothing in this section limits any mandatory consumer right regarding return costs.
16. Failed Delivery, Refused Packages and Returned Shipments
Customers are responsible for providing complete and accurate delivery information and making reasonable arrangements to receive their packages.
A package may be returned to the sender because of circumstances including:
- Incorrect or incomplete address information;
- Repeated unsuccessful delivery attempts;
- Failure to collect the package;
- Refusal of delivery; or
- Other delivery problems.
If a package is returned, please contact our customer-support team.
Depending on the circumstances, additional shipping costs may apply to a requested reshipment where the failed delivery resulted from incorrect information or circumstances attributable to the customer.
If the delivery failure resulted from an error attributable to Heyuseful or the carrier, we will review the issue and provide an appropriate resolution.
Any refund or reshipment will remain subject to applicable law.
17. Cycling Product Compatibility
