Update: the one in the coupon book is for a sonic spinbrush, so you cannot stack with this deal. Without the coupon in the coupon book, you may be able to snag it for $1.99 after printable coupon and RR. Still a good deal for someone who need it.
FREE-- Spinbrush + $1 moneymaker at Walgreens (12/4-12/10)
Here is how:
-- Buy 1 Sonic Spinbrush = $4.99
