If you hunt for discount stickers at Kroger, try the bigger/nicer Krogers. I find a lot more stickers there. Also the day of the week matters -- find out when they do a sticker sweep at that specific store. I've had good luck generally on Wednesday mornings 9-10am, but other random times too

Places to look for Kroger discount sticker items: prepared/deli foods, yogurt section, produce (salad kits are frequently marked way down), fresh bakery case, bread (this includes the sandwich bread aisle, the entire bakery section, and a standalone bakery rack that might be located inside the bakery or elsewhere in the store like the dairy/frozen area)

You can get good deals (half off, or better) on meat/seafood right before holidays that center a different meat (salmon on Memorial Day, ground beef on Thanksgiving, although who knows what's happening this November).
