They are a great way for a seller to realize many times the price they paid for an item.
For example, take a look at this closed auction.
http://pa.egunner.com/index/detail?auction_id=5087
The final price of the gun was $40.73
The winning bidder used 273 bids for $177.45, paid $40.73+$15 shipping. That persons total cost for the $700 gun was $233.18, a pretty good deal.
Now lets look at what the seller made, to keep it simple we will use the cheapest bid (bought in large bulk purchases to save bidders money) of $0.65.
It took 4072 bids for someone to win. 4072 x $0.65 = $2,646.80.
Add that to the purchase price, $2,646.80 + $40.73 = $2,687.53
(Not going to worry about the shipping costs.)
So at the end of the day, seller made about $2,687.53 on a $700 gun (not even considering that they do not pay MSRP for their guns, so profit margin even greater.), that is almost 4 times the retail value or about $2,000 over retail.
They sold $2,469.35 worth of bids to folks who did not win anything, zero return for their money, they just got to play the game
Awesome deal for the sellers.
Lot of folks contribute their funds to someone else getting a good deal. You can win with the system if you get lucky. First you have to commit to buying a lot of bids and using them all up if necessary. Next you gotta hope you are not going head to head with someone of the same mindset (and an equal or greater number of bids to use), as you get farther into the process you get so much money invested you don't want to toss it away, so you gotta keep pushing. Think of it as a game of chicken with your bank account, who will break first and lose. You may win with a good price, or lose a lot of money in the process and not get anything, pay close to retail or even pay over retail to avoid a greater loss.
Some folks like gambling. You think the casinos in Vegas get this kind of return?? LOL.

They got over $260 for a $50 store credit.
Winner spent over $30 to save an extra $20.
Seller lost money here, someone got a heck of a good deal.
