I thoght that eBay specified that paypal had to be a payment option.
ebay will want people to pay with paypal as they own it, and get a percentage out of it.
The seller might just feel happier staying within the woolly cotton world of paypal and ebay.
Indeed the worse than can happen is a non-payment relisting, but possibly the seller experiences a lot of buggering about before it gets to that, and it takes both parties to agree to a cancelled transaction (or a set amount of non-payment time to pass)
So if the buyer (speaking generically, I’m sure you’re on the level, but the seller doesn’t know that) says, I’ll do a balance transfer to you, but not now, when I get paid. The seller has to wait. If after some time the buyer hasn’t paid, but doesn’t want to cancel then the seller is a bit stuck with an item s/he wants sold
Without knowing what the other buyer bid, you cannot know you’d have won.
If bidder one bids a 1000 on a 100 item
then bidder two will need to bid more than a 1000 to win
If there’s no bidder two, then bidder one wins for 100
Seeing something sell for (say) 100 and thinking you could of won it for 101 isn’t necessarily accurate.
