And I believe PayPal's fee percentage has just risen...?
Not only that, but PayPal is holding the payment amounts for 21 days in the case of many sellers. It makes things very difficult for the unfortunate sellers who must shell out the final value fee, the cost of postage, the item itself, and still be left WITHOUT THE ACTUAL PAYMENT for almost a month after the sale. Add to that the increased fear that a difficult buyer may try to use the Money Back Guarantee (which has in more than one instance had the seller out of pocket for the item cost, postage cost TO and postage cost FROM the buyer, and WITHOUT THE ACTUAL ITEM BEING RETURNED TO THEM) to their advantage, and it makes me wonder how anyone has sufficient courage to risk selling on eBay at present.
Mind you, if one's buying an item from an established seller who is unlikely to have the 21-day-hold and is selling as a business, and the postage cost is ridiculously high, it would certainly deter me from buying from them - unless the item were a one-off hard-to-get incredibly rare sort of item that I desperately wanted...
