It is a trap. Ever notice how one week you might see some really fantastic RR or ECB offers at Walgreens or CVS? Before you invest your money into those deals, take a sneak peak at the next week’s sale ads. Catalinas (which are basically a store credit) usually have a 1-2 week expiration period, and if you don’t use them, you’ll lose them. If you do not find anything you need in the future sale ads or any deals where you can roll the catalinas, it isn’t worth your initial investment of money. To view the previews and future sale ads, go to www.iheartwags.com and www.iheartcvs.com .
