Food rebates are always nice to find. You can try 100 Calorie Right Bites Keebler White Fudge Dipped Pretzels for free. Print the rebate form here.
You'll need the token from the package, so be sure to save it to send in your submission. This try me free rebate doesn't expire until 8/31/2012, though it has the 'while supplies last' caveat listed below that date.
