Online shopping can be dangerous but it doesnít have to be if you know who to trust with your credit card. Before buying online with an unknown merchant I always visit ResellerRatings.com first to check out the stores ratings. http://www.resellerratings.com/ Click on the Store Ratings tab at the top right and then enter the Stores name in the box. The results page will show the Overall Customer Satisfaction Rating for the last 6 months and the lifetime ratings, and below that you can read the reviews of the company to see if you want to do business with them.
You can also use the site to find the best prices on items and Comparison shop different stores. They also have an extremely active forum. As an aside, for Tech related purchases I always shop Newegg and highly recommend them.
