One thing you can obtain easily to help build credit are gas credit cards. Use whenever you buy gas and pay off immediately and you won't be hit with their insane 20% rates.
Also, find a cellular place with a 1 year contract and get a phone. Drop down to the lowest plan if you really don't want the phone, but if you're willing to put up the $20 some a month, it'll help establish that you pay your bills in full and on time (if you do actually do this.)
To be honest, you probably don't want a CompUSA credit card anyway. What can you get there that isn't ridiculously overpriced? On top of that, there isn't much you can buy there that doesn't depreciate fast enough for it to be worth paying interest on those prices. I think a place like best buy would be better if you can get it (yeah yeah, BB sucks... etc.)... buy a couple DVDs or CDs or something from time to time and pay your bills properly and that will help.
If you have a parent would excellent credit, try and talk them into a joint application for a card. Buy a few things with it for a year or so, pay your bills, and then see if you can drop them from the card.
I'm no credit expert, but these are a few of the things my dad suggested to me as "reasonable" ways to build credit while I'm in college.
Keep a few things in mind no matter what you do:
-Pay the bills on time, everytime, AT LEAST minimum balance due. Adding more or paying in full is a better concept than paying the minimum.
-Just because you have the card, doesn't mean you NEED to use it. Yes, in order to gain credit recognition, you'll have to use it some, but don't buy just because you can.
-Start small and work your way up. Be careful of crappy interest rates and try not to keep balances on anything with bad interest rates.
-Read the small print.
Someone is more than welcome to correct me if I'm wrong on anything, and please don't take my advice without find out a bit more. Credit education is a WIP for me.
