I had my first experience today of a buyer winning more than one item under the Simple Delivery regime, and it is not great. It is all a bit opaque, but each item individually was a large letter under 1kg, which I think means buyer pays ebay £2.25. The buyer paid a total of £2.87 to ebay (the seller never sees this money), which I think is ebay deciding that I now have a 1kg-2kg large letter. The combined items weigh under 400g, so basically they have overpaid. The customer is a repeat buyer so I have refunded the 62p from my own funds as a gesture of goodwill.
It is not the amount, but the principle that is winding me up. What if someone buys 5 items and then demands a refund? Surely there has to be a way of a seller stepping in to confirm the postage details (size/weight) before the buyer pays. I know that the orders can be cancelled and then relisted as a single item and hope the buyer still decides they want them, but I shouldn't have to do that.
As a sidebar I am, like many, stuck with £300 of Large Letter 1st class stamps I cannot use, other than selling at a loss somewhere like ebay.
Not a happy bunny.
