Free Tylenol and tomato paste with coupons

Here are two more great reasons to clip coupons -- free products! By combining recent coupons with sales (a technique called stacking), you can score free Tylenol PM at Walgreens and free tomato paste at Walmart. Here's how it works.

Tylenol PM is on sale for $2.99 at Walgreens this week. Print out a $2 off 1 coupon when you register for the Tylenol calender. Also use the $1.50 off 1 coupon from the Walgreens March Coupon Book.
