I just got a text message coupon from "Tropical Smoothie Cafe" which is like a breakfast/lunch place local to me. I signed up for this thinking it would be crappy, but I'm surprised that they offer different things like "Free Soup if you show this text message Sat,Sun,Mon. of this week" I thought this was pretty cool, and allows for less paper use and you wont lose your coupons unless you delete the text for your phone breaks somehow.
Anyone hear of other companies using a similar coupon approach?
