I don't have a dog, but if they pay me to buy dog food, I will buy it. I have family members with dogs, so it certainly does not go to waste.
Currently, there is a $3 off ANY SIZE insert coupon for Purina Beneful dog food in the 3-21 SS. Petsmart sells a trial size for .99(found on clip strips around the store) so:
I purchased 10 @ .99 each = $9.90
1 Science Diet cat food $27.99 (with Pet Perks card)
-9 $3 Beneful coupons (I gave him 10, but he missed one)
Tax = .90
Cost oop : $11.79 for 17.5 lbs of cat food!
Thanks to HCW for the heads up!
