Direct sales vendors such as Dell and Gateway 2000 are significant players in the computer market. These firms sell direct from the factory, and tend to combine good prices and attractive service policies. Mail order stores are most suitable for very knowledgeable consumers. Mail order offers the best bargains, but also the greatest risk of receiving a sub-par system. As a result, businesses buying through mail order should be careful to investigate both the firm and the model before buying.
Computer stores are often a good source for advice and technical help.
Most computer dealers stock a wide number of models, plus most important peripherals. However, dealers tend to be more expensive than other sources. VARs generally have the highest level of knowledge about systems, particularly in setting up computer networks. If you haven't purchased a computer in a while, current pricing may pleasantly surprise you. Although you may find the features or support policies unacceptable for the workplace, a low-end model may be fine for relatively limited applications.
