I thought that when a buyer selects "Buy It Now" (on a listing where immediate payment is NOT required) should pay asap as the listing remains active until it is actually paid for. Example: John Doe chooses "Buy it Now" at 10 am, but waits several hours or days to pay. Sally Jones comes along at 11 am and buys it now with immediate payment and John Doe loses out. If this isn't true, would someone tell me, as I can't seem to find this in any discussion thread here or on eBay. Thanks,

Hi JeanieB,
If you did not have Immediate Payment Required, the listing is ended when the Buy it Now is clicked, and the buyer will pay whenever they get around to it. (unfortunately) In your scenario with John Doe etc, that would only work if Immediate Payment had been enabled.

I would just send the buyer an invoive and hope for the best
