I don't think its wrong. If it is was that frowned upon I don't know why the government would give you back the money in the first place. The only things I've ever used financial aid on was for fixing things or helping me out through college. I bought a macbook air because i didn't have a computer for college and quite frankly its the best computer I've owned. Ive also fixed me car from being an utter POS to drivable all through financial aid, and I don't feel like I've done anything wrong.
