Took the advice of another poster and used a Try a free bag of Hills Science MQ found on the bags.
Found a 3.5# bag, regular price $15.99, got it for free (x tax).
Then used a coupon I printed from coupons.com for $10 off any 4# or larger cat food.
Purchased Canidea 4# reg price $12.99, less $1.30 Pals Card = 11.69 less $10 coupon.
$1.69 for both bags. Or 85 cents each.
Tip. Do it in 2 transactions.
