I used (4)$8 Hills Science Coupons & (1) $5  Petsmart coupon. Free coupon for the Cats Pride cat litter. The Tide stain release $5.99 at Kroger, I loaded $3 on my Kroger card and had a $3 coupon making it free.  The 24 piece food storage was $1.50 each at Kroger.  (When I went to Pet Smart the cashier said, you have to get something $8 or more. I told her all she had to do is allow for the $5 only and write it on the coupon.)
