$2 Purina coupon at Dollar General = cat food for $2.75 a bag

Have a cat or dog?  Check out Dollar General as mine had a tear pad of $2 coupons good until 7/31/2012 that were good on:

1 package of Purina Beneful dog food
1 package of Purina Kitten Chow
1 package of Purina Cat Chow
or  Purina Tidy Cats brand cat litter, any size or variety.

I didn't price the Beneful, since I don't have a dog, but I did grab a bag of Cat Chow for my cats.  Dollar General's price on the Cat and Kitten Chow is $4.75, so after coupon, it was $2.75 for the bag.  Though the coupon's left side has a DG logo, it is a manufacturer's coupon and it does not have language stating it must be used at a Dollar General.
