Here’s one such exception-worthy deal:
EOS Organic Lip Balms are on sale 2 for $6 this week. Plus you get a $4 Register Reward when you buy two, making it just $1 each after RR.
Helpful tip: Walgreens only gives you 2 weeks to use (or lose) your RR. Since I shop there so infrequently, I make it a point to use my RR in the same trip.
