BOGO with clearance bags and a high-value coupon, that’s what! Through 2/25, PetSmart has Purina on BOGO plus there’s a $3 coupon in 1/29 rp. Only 25% off two bags, so not the huge savings I’ve encountered in prior visits, but these four bags ($8.69 shelf price) cost me $3.43 plus tax. Expiration date on clearance is July, 2017.
