I'm a buyer - not a seller - and, because of the way I shop, I really prefer "BIN" for most of the auctions I'm looking at. I go on Ebay for very specific items, usually related to my DD's theater activities. So I need a particular show CD or a unique item of clothing for a costume, etc. When I find it, I just want to purchase it. Don't want to worry about checking back or getting outbid. I actually wish that an auction I'm looking at now had a BIN - I'd have purchased the item already.
