Hurry on over and log into your PetSmart Pet PetPerks account. Click under the Blue tab that says PetSmart Coupons and you will see a coupon for $5 off your next purchase. This will make for a FREE item!
Also, if you do not have a PetPerks account you can sign up now and still see the savings in your account. I just tested it out as I did not previously have an acount and the $5 coupon showed up.
(thanks Palmetto State Saver!)
