I had left my Yelp deal receipt at home but figured I could just use the deal from my Yelp app...WRONG...the store only would not accept it from my app. The sales person said they had to have the hard copy. So, tell me, what's the purpose of the app if the stores don't accept it? Castle shouldn't offer the Yelp deal if they're not going to honor it the way Yelp sells it.
