TripleClicks is a one stop shop auction site. TripleClicks features regular auctions with third party buyers and sellers, much like eBay, but it also features its very own penny auctions, called Pricebenders.
In order to participate in auctions on TripleClicks, you must purchase TCredits. TCredits are available anywhere from $1.99 for a single TCredit, to 29 cents per TCredit for a pack of 200.
You use TCredits to list items for sale on TripleClicks, but also to bid on items in their penny auction area called Pricebenders. Just like regular penny auctions, each bid raises the price of an item by 1 cent and extends the clock. The final bidder wins.
If you sell an item on TripleClicks, the sale money will be placed directly in your TripleClicks account and can be used immediately for purchase of other items for sale on the site.
