not sure if this falls into the free category, but right now if you buy certain pepsi products from loblows (superstore). If you spend 20 dollars you will get 30 dollars back in loblows gift cards. You just have to send the receipt in with the mail in rebate forms. The only problem is most of the mail in rebate forms are gone, so you will have to look around superstore or ask the supervisor for them.
