I'm sure GameStop and EB would both carry it (used at least). The best thing to do would just be grab a phone book and call them up, though I don't know how many locations there are around Purdue. You might have better luck when you are back in Cincy. If I am at any game stores I will keep a look out for you.
I will be back in town this weekend. Don't want to be be here this weekend. (Long story.) At least this way i will get to see the Bengals rip the Steelers a new one!
I'll check out the local game stop while im in town.
