Hersey's is pushing a new product -- bags filled with pieces of your old candy favorites: Almond Joy, York Peppermint Pattie, Hershey's Special Dark -- along with Reece's Pieces (which you've probably already tasted).

Now you can get a free bag of one of the four pieces-types when you follow these three steps.

1. Buy a Hershey's candy bar (including Reese's Peanut Butter Cups, Almond Joy, Hershey's Special Dark, or York Peppermint Patties).

2. Mail the complete wrapper with a form available here to:

Pieces Wrapper Reward Program
6961-15
P.O. Box 750792
El Paso, TX 88575-0792

3. Wait 3-5 weeks for your coupon for a free Pieces candy product worth up to $3.69.

Don't delay! Hersey's is sending the coupon to the first 25,000 people to print the form or until the offer expires on Feb. 10, 2010. Forms must be postmarked by Feb. 17, 2010 and received by Feb. 26, 2010.

Caveats: one submission per envelope. The coupon itself expires on Aug. 1, 2010. Limit one coupon per person/address/household.
