Many people love to buy things online because it is so convenient. The favourite places of shopping online seem to be major online such as eBay, Shopping.com and MSN. For eBay, the most obvious thing that you can consider the quality of seller is feed back for the seller.
You probably have to check all comments regarding their service. Check out the comments made. If the majority of the comments are negative then this is a good indication that you don''t want to deal with that seller........BUT.......you can't always count on the feedback whether it is Power Seller or not, whether they have 99% or less. They can still slip in fake handbags online and get great feedback for them. Why? because the buyer has no idea they got a fake.
