I haven't shopped at Walgreen's in awhile, but my mom told me I had to do the Melatonin deal.  It was on sale for $3 and there was a $3 printable coupon making it free, in addition to that, it printed out a $3 Register Reward (or Jingle Cash, as they are calling it for the holidays).

All in all I paid $1.32 for three bottles of Melatonin, two sticker books and a Hershey Bar (Ava requested the chocolate bar at checkout, haha)...and got back three $3 Register Rewards.  Profit of $7.68.
