Halo 3 $10 at Gamestop Good Deal?

I was just wondering if this was a good deal or not. I've kind of reached my video game spending limit this month since I just picked up a 360, but if this is a good deal, I may want to grab it.

Also, I'm only planning on getting one Halo game since I don't see a point in getting all the iterations of them, so that being said, should I spring for this or just wait for a price drop on Reach?

depends if you've played the others in the series. if yes, $10 isn't too bad, even though i think there are a lot better shooters out there. but if you haven't i would just save for reach or get bioshock 1 or 2 i believe they're both $10 each as well.
