Through May 25, don't forget that milk is $1.98/gallon at Kwik Trip! This is the price for the milk sold in bags, so that's $0.99 per half gallon bag (skim, 1% and 2%).
If you prefer to buy the plastic gallon jug, then it's just $2.29 per gallon.
And this past week, I noticed that one pound packages of (salted) butter are only $1.89 at our Kwik Trip store. You may want to check your store, too!
