Don't take it personally, they're only exercising their statutory rights, the same rights that makes online selling so appealing as it attracts buyers with confidence. If this has you wound up don't even think of selling on Amazon via FBA!
Its all great when they return items that are of low value, but my items are all high end tech and phones over £200. Surely people think long and hard before buying it, just to change their minds lol.
Plus, i'm not wholly against returns, but with high end tech, my buyers return it in weak packaging which can damage the item in transit.
The reason why Paypal does not refund fee is that its merchant account provider would not refund PAypal.
also when you refund ,it is a new transaction, a credit,and there are fees involved in doing so.
