Coupons.com and printablecouponsanddeals.com (maybe net? Something like that… It’s a grey and blue blog style website) are good places to start. If you don’t mind Purina products, projectslimdownpets.com has good ProPlan coupons too. They reset every so often. Some of the coupons on their are currently unavailable, but check them often any ways.
You can also just look right on the retailers websites. If don’t mind it, Pedigree is doing an adoption drive event, and of you print out a form, fill it out, and send them a copy of a vaccine receipt (among other options), they will send you a coupon for a free bag up to $10 (I opted to get the sensative systems one, the better of their craptasic foods– paid like 2 bucks for it after the coupon) and free any four cans up to $5 (for the best value, get the big cans! ;)).
