Kroger has a display selling candy bars for 50 cents each--M&Ms, 3-Musketeers, MilkyWay, Snickers, or Twix. Affixed to the top of the display is a stack of coupons for 50-cents off of 2. (You need to buy alin sets of two but you can mix/match)
2 candy bars: $1.00 - $0.50 = $0.50 (for 2)
Please post if your kroger has the same. Our Kroger in Kentucky has it "hidden" over by the deli.
