My opinion is that auctions are pretty much dead these days, unless you are selling very unique items. I have noticed on many auctions that the bids go up by one or two dollars only each time.  I started out selling with auctions, and almost immediately, had a non paying bidder, that had only bid three dollars above the starting price, and one dollar above the underbidder.  I think a lot of people are very time poor these days, and would rather BIN. That includes me.  I find it rather annoying when I have to get up at 3 am to snipe something, I would rather a BIN any day.  Since I sell only BIN  these days, I haven't had any more non paying bidders.  Some seem to watch forever, before buying, but that is ok, as least it gives them time to think and not rush in, or get carried away on an auction.
