Ok 2 weeks ago when I got Ping his food they charged me to much and I am just now noticing this. I bought 5oz cans and they charged me for 13oz cans. And normally I would notice such things but I was in a hurry. Next time I will pay closer attention. The 5 oz cans are .93 cents but the 13 oz cans are 1.79 so its a big price jump. Its the duck/oatmeal cans that he didn't like. So hopefully when I go in tomorrow to exchange the ones he didn't like I can get my price difference back.
