Materials cannot be returned for refund. Exchange is only possible as follows. Thanks for understanding.
(a) If an item arrives damaged or defective and you notify us within 15 days of delivery via email
(email@example.com), In this case, we will replace it at our expense, including the shipping cost. We may ask you to return the damaged/defective item before we send the new one, and would give you mailing instructions.
(b) If you made an error by ordering an incorrect item, we will be happy to exchange it for a different item at the same or greater cost if you pay the shipping cost in both directions (returning the incorrect item and the new outbound shipping for the correct item), plus a $10 handling fee (it is $10 for any number of items that you are exchanging at the same time, not $10 per item). For this type of exchange, you will need to obtain a return authorization number before you ship it back (email firstname.lastname@example.org).
