Get a free plate from Tyson's by purchasing three specially marked packages and entering the codes via their Facebook page. Note: You need all 3 codes to enter at one time, so save your codes until you have enough.
Things to know:
This offer is limited to the first 10,000 redemptions; and
This offer expires 3/31 (or before if redemption level is met).
Perhaps a good thing: Since there's only 10,000, maybe someday in the distant future the plate will be collectible and worth something ;)
Bummer: The code is on the inside back of each package. That means you don't have a lot of time to purchase 3 specially marked packages and you'll need to open them all at one time. Hope you like chicken!
