I had been contacted by a customer, who purchased a memory card but received a used, product from, a different brand and even the FNSKU sticker which does not belong to our store.

I suggested opening a return on Amazon as per our contract with Amazon FBA they provide customer service and manage returns and refunds.

However, he had been told that "They are unable to accept returns of this product due to its condition and nature (electronic storage device)."

We are getting dozens of memory cards returned every day, so it is a returnable item.

Has anyone seen a FULL list of non-returnable items?

The one here is not too exhaustive

Any suggestions?
