Starting November 1st, there will be a new Holiday Savings booklet at CVS that lists out all of the ECBs deals that they will have over the holidays.
On page 84 of this book, there is a $4/$20 coupon! I would recommend getting there as close to November 1st as possible because booklets with coupons like these get snatched up pretty quickly.
(Thanks, I Heart CVS!)
If I get 2 books, can I use both coupons, or can I only use it once?
