Qdoba is offering coupons for free Mexican fare when you play their "Craft Your Life" online game, which is basically a very elaborate version of MASH. I think everybody gets a coupon for a free drink when you buy a "Craft2" meal item, and then they're giving away thousands of coupons for free food if you're a lucky winner.
The gist of the Craft2 thing is that you mix-n-match single items to create your own meal, or something, I guess. For free food, I'd try it, but all I got was a loser drink coupon. Then again, I'll (apparently) be living in a mansion in Jakarta with my pet flying squirrel and my boyfriend Hipster Hayden, so who NEEDS their free food, anyway?
