Finding a coupon

So I google new food deals all the time and I always get sent to smart canucks because of how great a site it is ;)

but trying to guide through the site confuses me a bit.

what I am trying to do:

Find coupons/promotion codes for fast food restaurants in my area. When I did a search, all I find are deals at grocery stores. ie: Restaurante pizza coupon.

on google I type " dominos pizza code " and this site popps up. Is there any place where I can see deals of different stores compared against each other?

Thanks a lot :)
