Our local Kmart has a deal that everytime you spend $50 you get a voucher for .30 cents off gas at Sunoco. You can also add these slips up. This week only they are also offering a free $5 giftcard with the purchase of a $25 giftcard. So for Christmas I purchased Giftcards for my family. I save $1.80 off my gas at Sunoco and filling it up for 20 gallons and I received $40 in free kmart gift cards that I'm going to use for stocking stuffers. I also got more coupons that printed out of register that if I spend $100 I get $10 in shop your way rewards.
