Well the Subway on campus here said they'll be continuing the coupon thing until the end of August, so I just got mine redeemed. In retrospect, I should have gotten a pricier sandwich than their veggie.
Yeah, the Subway near my house is still doing it. They are thinking of making it so they can swipe a card and put the points on, or even storing them in the computer database (cash register). They are just looking for a good method I guess.
