The margins in computer hardware are cutthroat at best with sellers making only a couple percent markup on all goods sold. Fortunately, most outlets do not have to own the computers. With these miserable margins, many of these shops have started up service operations. Mr. Fan, at OnSale says he can make max 3% on a laptop, and even less if he is setting up an office and selling several machines. These days he has people proficient in English and superb in English and Chinese Windows, and so he has targeted foreign enterprises requiring computer network setup and management. It's a deal that works well for everybody. So if you're in need of a computer or networking, go by or give them a call, and Mr. Fan will surely be able to hook you up.
