Go here to grab a coupon for $5 off a $5 PetSmart purchase. It is being reported that you can get anything $5 or less for FREE! It is intended for PetPerks members so get your membership.
This coupon can also be used at PETCO as a competitors coupon. Combined with manufacturer coupons you can get really cheap pet supplies if you want to go over the $5 limit.
Thanks My Pet Savings!
