Micro Center is always running sales, and sometimes you can get great deals. They carry a bunch of parts for PCs, so if you're planning to make your own computer it's great. They also carry a lot of MAC parts as well. It's not just comptuer stuff though, as they carry video game consoles and dvds. It's a good store to get help w/ your computer problems as well, because the staff is pretty helpful.
I remember in high school, I used to buy my required readings and cliff notes at Chapter 11. It's a little cheaper than normal bookstores, but you can get better prices online. But for a bricks and motar store, it's good.
Big League Barbers is one of the better places, for guys, to get haircuts. It's just a normal haircut, whatever you ask for, but you get a nice shampoo and a massage at the end. It's great! It's not too expensive as well, with their normal haircuts running for about $13. It may be a little more than Great Clips, but you're getting a much better haircut and better service.
