I read about this over at mashupmom.com
Sign up to receive a free sample box of products from USPS--yes THAT USPS, the United States Postal Service of all things. If selected you will receive a box of sample goodies in May (current list shows Reeses, Nescafe, Aveeno, Secret, Ben-gay etc but they may differ). I know you're already thinking "great, more junk mail," but in this case you might get a neat item you haven't tried, and typically samples come with coupons. If you don't like the items, consider donating them to a shelter or pantry.
