Fry's Electronics is the mecca for your electronic needs. The have a variety of electronics, everything TV's to hard drives. Everything is well organized, it has to be since the facility is so huge. In the Plano location, there is even a cafe that sits in the middle of the store, so you don't even have to leave if you get hungry or thirsty (I think they like it that way). In addition to being large and having alrge variety, their prices are extremely competitive, and usually the cheapest you can find in a B&M store. This is the store I always go to first for my electronic needs, and it should be yours as well.
