It's a sad fact of life that some folk started doing this - and the sellers have to take responsibility for it
If they didn't agree to this practice, it wouldn't happen. :grrr:
And now a lot of folk, who heartily disapprove of doing it, are driven to do it themselves if they actually want a piece, in order to pre-empt somebody else doing it.
If you find you're seriously interested in a piece being sold by somebody who will do it, it might as well be to you as somebody else.
I hate it, I really, really hate it. But I have done it once. (not this bit).
It was rather nerve-wracking - I knew from the seller's willingness to close the auction they were already a bit dodgy.
But - if it's up with a BIN - there is still a window for somebody else to pop in and click on it.
(I know, it's happened - the potential buyer was furious!
