I'm a freaky couponer and our store has what's called Just For U pricing. it tracks what you buy and you get lower prices every month or so on things you buy. Like today I got boneless skinless chicken breasts $1.88/lb. That price is good thru the end of the month I think. doubled up cereal sales (1.99 check) with coupons $1 off two.
In general tho I don't buy anything that is prepackaged or single serve or anything. Heck my kids think juice is a treat too LOL
