If there ever is a defect with any of the prints, we will reprint and ship that item at no extra cost. All you need to do is send the order # and a picture of the defect to email@example.com and we will send out a replacement.
We do not accept any returns or exchange items that were ordered incorrectly (e.g. size/color, wrong address, or an incomplete address). Orders sent back to our print centers cannot be resent since they don't have space to store unwanted or returned items. You can have the customer send the product to you though, and you are welcome to refund or put in an order for a new product.
We also do not refund orders that have been verified as delivered by the tracking carrier. Best to have your customers contact the local post office for those cases.
