Dr Pepper/Diet Dr Pepper Deal at QT's

Right now, many QuikTrips have coupon pads hanging on the doors in front of the 20 oz Dr P and Diet Dr P. The coupons are for $1 off 2 20oz bottles. The price I have seen makes the soda 2/$2 after the coupon..I imagine it is that way pretty much all over the Tulsa area :)
