How to return and refund

We have a 30-day return policy, which means you have 30 days after receiving your item to request a return. To be eligible for a return, your item must be in the same condition that you received it, unworn or unused, with tags, and in its original packaging. You’ll also need the receipt or proof of purchase. To start a return, you can contact us at support@gstpautoparts.com. If your return is accepted, we’ll send you a return shipping label, as well as instructions on how and where to send your package. Items sent back to us without first requesting a return will not be accepted. You can always contact us for any return question at support@gstpautoparts.com.

Shipping & Delivery

We can ship to virtually any address in the world. Note that there are restrictions on some products, and some products cannot be shipped to international destinations.

We will process and ship out your order within 1-2 business days upon clearance of the payment. You will receive a tracking number as soon as your order has been processed. “Business days” for ship-out or delivery timeframes refer to Mondays through Fridays only. This does not include Saturdays, Sundays, and holidays that fall on a weekday when counting business days.

Gstpautoparts.com does not ship to PO Box, mailbox, HI, PR, AK, GU, and APO/FPO addresses.

Delivery Timeframe

Most orders are processed for shipment or leave our warehouse within 24-48 hours of your order confirmation date unless otherwise specified. Delivery or transit times will vary depending on the size of the package and the delivery location. Small and medium-sized packages are generally delivered within 3-5 business days (excluding weekends and holidays) from the date the packages leave our warehouse. In addition, there may be instances in which orders with multiple parts/items will have multiple tracking numbers depending on which warehouses the parts/items will be coming from. Please note that we disclaim all liability for orders that do not meet anticipated delivery dates.

When you place an order, we will estimate shipping and delivery dates for you based on the availability of your items and the shipping options you choose. Depending on the shipping provider you choose, shipping date estimates may appear on the shipping quotes page.

Please also note that the shipping rates for many items we sell are weight-based. The weight of any such item can be found on its detail page. To reflect the policies of the shipping companies we use, all weights will be rounded up to the next full pound.

Expedited Shipping

Expedited shipping is available for most small and medium-sized packages for additional charges.
