Decisions, Decisions

So I just barely started my Spring Break and i have some decisions that I need to make. The main decision is whether or not I should use my $50 gift card to Best Buy and go buy either Crisis Core or Chains of Olympus. Although I have had my eye on FF: Tactics for a while. But the dilemma is that I really want a PS3. I mean I really want a PS3 and the only way I get money if from not using my gift cards because my mom doesn't give me an allowance. Well if anyone out there has an idea on whether i should spend the money or save it leave a comment. Thanks for reading my post. Peace
