I asked the manager at Pet Valu and he said if you buy a flat, 24 cans, they'll give you a discount. Here it was working out to about 7-9 cents per can, and Wellness was on the shelf (bigger cans) for 1.59. He said the 24 didn't have to be all the same flavour either.
I bought an assortment to see what my Cookie likes, and next trip I plan to go for 24 at a time!
