The only downfall with eBay is that you have to registar and when you do, you have to put in a credit card number. It's a security measure to make sure that no one gets ripped off. Your (or your parents) credit card will NOT be charged if you bid on something or win an auction. You pay the seller in cash or money orders and they ship you the product. (Unfortantely you pay in US funds unless you go to eBay Canada but they have less stuff). The chances of getting scammed are slim to none (I have never had bad experiences and have been on eBay for almost a year). You can also sell things and make tons of money (remember it's US money...so for my fellow Canadians out there: big $$$!) The credit card is only charged if you sell something and it's a VERY small charge.
