At the store where I usually shop I always buy Pixel a 3-pound bag of the more high-end, "more nutritional" catfood. I only have one cat, but I also feed a couple of feral cats. Still, the 3-pound bag lasts til my next payday, so the extra buck-and-a-half is no big deal.
So anyway, the store gave me a $3-off coupon last month for the brand of catfood I usually buy, but this month that brand and all the other high-end brands weren't there, neither dry nor canned. All they had was the cheap stuff, and there wasn't much of that. But the cashier was nice enough to let me use that coupon. And sure, that was nice, but since it was one of their coupons, it was only fair, really.
Pixel doesn't seem to mind what brand I get. He's more hog than cat.
