I like the free auctions but you can only win bids. First penny acution I played and won a IPOD NANO (first win ever) but I can never get the hang of winning on this site
Really like Quibids - especially lightning auctions. The only trouble is so many bidders its hard to find good wins anymore. There are never any "sales" for bids and voucher bids do not count towards BIN.
Games are a fun way to win bids - they are difficult to win and if you bid more then the item costs and do not win you cannot buy the gameplay.
My favorite and longlasting penny auction site. If you are able to play during off hours you have an excellent chance for a good deal with always free shipping. Only problem is too many bidders are willing to prove they have more money and bid way beyond the cost of the item just to win. Its supposed to be about getting it cheap not spending the most money - so the auctions are long and seem endless.
