Walgreens Three Musketeer RR Deal 4 for .49

There's a Register Reward deal at Walgreens that is sweet (LOL). I haven't seen this in the flier but it works. 3 Musketeers Truffle Crisp and Three Musketeers are .49 with an in-ad coupon from the weekly flier (see picture at left). Buy 3, and get a $1 RR. Buy 4, and get a $1.50 RR.  Please report your experiences on Chat. The coupon you're looking for in the flier is good for any Mars candy bar for .49. In the 12-page flier, it's on page 3.
