One of my freinds just sent me the link. I did this last year and the coupon
I received are very good. Especially $3 off chips and $2 of any pepsi drink.
Download the rebate form and mail it out with UPS by 02/17/2009. http://pepsistuff.com/2009superbowl_webform.pdf
Update: next week, cvs will have buy $20 get $10 extra bucks on pepsi stuff. So you will get even more now.
