Do you have a Pet Perks card? If so you can register on Pet Smart’s  website and snag a $5 coupon! Bloggers report there is no minimum purchase required and the coupon expires 5/1. Just check under “Petsmart Coupons” and it should be there.
As soon as I have a chance I am going to register mine and see if I get a coupon!
Thanks Mrs. Moneysaver !
