welcome to listia, that is what this site is all about. you list your items that you no longer want, people bid on your item with credits (no money) you take the credits that you win and bid on the items that you want. (like the lego's) if you are the highest bidder at the end of the auction you win. the 1st thing to do is get your address verified so if you win anything the person can send it to you. all so get your account verified before listing items, this helps you get more bids. and because you are new when listing an item write your listia name on a piece of paper so people know you do have the item that you are listing. also when bidding on an item look at the sellers % rate. hope this helps.
