Qdoba sent me a coupon for free chips and queso for being awesome. It doesn’t look like there are any restrictions other than the normal ones and it doesn’t seem to be tied to me. My wife and I used one each today to get some and they were good. Try it yourself!
Keeping with the music theme I ran across some free MP3’s from Amazon earlier today. There is some random stuff in there but with 3200+ songs I’m sure you can find something. After all, the price is right. Check it out at Amazon’s site. My favorite so far is I was able to download the album A Sound Legacy: 60 Years of Folkways Records and 20 Years of Smithsonian Folkways for free. You can’t beat that! Enjoy.
