Prices are competitive with the cut-rate dealers, but you can bring the computer back when something goes wrong. Before buying a system, check to see if repairs are done in-house. Some stores also offer classes in using the computer. If you are a true bargain hunter, the best deals can be found on the Internet. First, watch out for auction sites.
Many auction sites are simply agents, selling merchandise for other companies.
While the auction site charges your credit card, it cannot promise delivery of the goods. Some auction sites can be very liberal with their description of computer equipment. Watch out for shipping and handling fees. Refurbished equipment can be a good value, but make sure the it is refurbished by the original manufacturer and carries a real factory warranty. And before buying any used or refurbished equipment, make sure you can return it, no questions asked, if you don't like it.
