I gave up on CVS awhile ago, since they never send me any coupons at all. And these type won't work with your card unless you had them e-mailed to you directly (unless a cashier pushes them through). It will say "not for card scanned." So, just be warned you may have a problem with coupons like this one.
I tried, but no luck. They said the coupon was not for my account...and it wasn't, so I couldn't argue with them. If they are out of the item, however, they should give you a raincheck even if it is a freebie.
