Many, but not all CVSs have a self scanner. You can price check sale items. Sometimes stores change over to the new Sunday prices Saturday evening, and you can scan an item to see if the new prices have been "turned on".
Best of all, you can scan your card and see what kind of qs pop out. After the first scan prints out, try scanning your card a second time because you might get more qs. Then try scanning a third time (three is the most times I've been able to get qs in a row), until you get the message "No more coupons today. Come back tomorrow."
Wow that's a great tip I always scanned it just one time for sure will try it again now
Thanks Misty for the heads up
