Hillshire Farms has a fresh taste challenge that is good until September 4, 2010. Buy a specially marked package that has a unique code and try the product. If it isn't the freshest you've tasted, you can take your unique code and get a $5 grocery card back by mail (be sure to save your receipt and packaging to do this.) If you agree that it is the freshest, you can print some coupons worth $5. So either way, it is $5 worth of value.
The terms and conditions are available on the Hillshire Farms Fresh Taste Challenge site, so be sure to look them over before you buy.
