Internet Shopping

I'm pretty sure that the best deals on the internet are on Ebay. What I do is browse carefully through all the offers and find one that has a really cheap ,,Buy it Now'' . Then I check the guys rating and if it's highter then 2000 I buy the item immediately. If I do find a better deal on someone that has a rating with like 200-500 I think twice before buying. I don't usually Bid on Ebay because I don't have time for all that, and usually in a good deal there are a lot of bidders. Also I check on Amazon and compare the price on Amazon vs Ebay. If a user has something that is WAY cheaper then the amazon price I immediately think it is a scam
