WHY IS MY ORDER BEING SHIPPED IN DIFFERENT PACKAGES?

If you have a multi-item order, each item may be shipped from a different international warehouse, depending on which one has them available the fastest. Alternatively, if an item is popular and on a bit of a backorder, we might ship your items at different times, in different packages, to prevent holding up your order and to get it to you as fast as possible! 

WHEN WILL I RECEIVE MY ORDER?

Orders are shipped out directly from any of our many domestic & international warehouses and they will do everything they can to process your order as fast as they can! Due to the popularity of our offers, please allow an estimated 7 - 12 days for your order to arrive in the USA (varies from product to product) and around 7 - 12 days for other countries (depending on the distance).

WHAT HAPPENS IF MY ORDER GETS STUCK OR LOST IN THE MAIL?

All of our orders are sent with insured shipping and handling. If an order gets stuck at customs, sent back, or even lost during the delivery process we will send you a new package with quicker shipping and full tracking, if possible. Please see our refund and return policy for when these might be applicable to shipping situations.

RETURNS AND EXCHANGE

We have a 15-day return policy, which means you have 15 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@crestsport.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.

Please inspect your order upon reception and contact us immediately if the item is defective, damaged or if you receive the wrong item, so that we can evaluate the issue and make it right.

Exceptions / non-returnable items
Certain types of items cannot be returned, like perishable goods (such as food, flowers, or plants), custom products (such as special orders or personalized items), and personal care goods (such as beauty products). We also do not accept returns for hazardous materials, flammable liquids, or gases. Please get in touch if you have questions or concerns about your specific item.
