I just had the experience of going to Bath and Body Works and showing a coupon (in the comments http://www.buxr.com/deal/bath-.....ody-works)
to the cashier on my smartphone and getting the discount. It is too rare when that happens, I think Fire+Ice may be the only other place I have done that.
What is your experience? Have you found stores willing to accept coupons and discounts presented in non-printed format? Does it seem to be store policy or just if the manager or employee feels like it?
Please tell us where. Perhaps this might be a nice wiki resource.
