I LOVE EBAY. I think the best thing about ebay is that there are so many products. Theres stiff competition among sellers which leaves the consumer with lower prices and you dont even need to leave home and put up with snobby salespeople to get what you need.
I dont buy a lot from ebay (im just a poor college student after all) but its a great place to comparison shop. If I could muster myself to wait for text books to come in through ebay, I would because it proves to be cheaper.
I wasnt going to start buying things on ebay, but I saw this documentary on tv about it because they assure the buyer that if the seller cheats them, theyd get their money or some type of compensation.
My favorite part is the fact that people leave feedback so that you know whether or not the seller/buyer is trustworthy. There have been many times when Ive seen a good product not sell because either the seller had bad feedback or had no feedback at all.
