Normally most people view Walgreens as just ether a drugstore or some quick place to pick a few necessary items or a snack. While I used to be in that population too... Since becoming more money conscious as a one income family... It makes you pay attention to those little quick trips. Those add up.
Walgreens has a program called Balance Rewards... You can save money by making points on certain items that you buy. They have also added points for healthy living. They give points for each mile you walk/run in a day. They also give you points for weighing in. The points add up pretty quickly and they equal cash in store.
