I just got one yesterday. I also get coupons on line and just learned how to get them on my Smart Phone.
I won't tell what store I was at as the employee who helped said they weren't supposed to do that. But there has been many times that I passed going to JoAnn's because I didn't have a coupon with me. Now that I can bring them up on my phone, I can always indulge. And I don't think I have ever bought just one thing with the coupon and walked out. I always see more things to buy.
Seems like stores should catch on that if they helped customers learn how to do to get their coupons on their phones, at least the technological-challenged ones like me, they would actually be increasing their business!
