This offer just popped up on Twitter (although you don’t have to have Twitter to get it). Head here  to get a $4.00 off of $20.00 coupon emailed to you. This says it is valid until September 15th, but the last time this was available it ended early.
You must have a CVS Extra Care Card to receive the coupon but they will e-mail you the coupon, so you don’t need a printer immediately.
Thanks For The Mommas !
