I go to Fry's whenever I need components, small parts and batteries for my computer and other stuff. They have a huge selection of parts and tools that most retail stores don't have, and at much better prices (get a decent set of cables for $4 that "Best" Buy charges $30-40 for). Half my computer is assembled from parts I got there. Their software prices are usually pretty good too.
Don't go to them for fully assembled consumer electronics (laptops, cameras, etc.), though. Their prices tend to be just as high as any other rip-off retailer... well, maybe not as bad as Best (Worst) Buy...
They get another +1 from me for being the only place I've seen actively displaying Pentax cameras, even if their salesreps are often annoying and clueless (aren't all salesreps like that?). I fell in love with the K-7's body after holding one at Fry's.
