I still think we need to do something like this. Im tired of people saying that high bid is "X", then I say "X+5", but then they reply less than a minute later saying "high offer is now X+10"
We need a site that will keep track of everyone's bids, and the bids are set in stone so you cant back out of your offer. It is unfair to buyers that actually want the product, and sellers that have their buyers back out of the deal.
this is a perfect example
I guarantee that the seller will have at least 3 buyers back out.
