Ebay Returns / Policies
If a buyer returns an item, it should be returned in the same condition in which it was received, and it should include all items that were in the original package.
If the returned item is used, damaged, or missing any parts, or is damaged during return shipping because it wasn't packaged correctly, sellers will provide a partial refund to account for the loss in the item's value.

Store return policy
We want you to be happy with your purchase, but if you are not, you can either return your purchase for a refund, or exchange.
Items should be returned in the original conditions without marks and signs of wear, otherwise minimum 15 percent repair/restore fee applies (per Ebay policies).
Please obtain proof of delivery when returning items as refunds will not be issued if items are not received.
