Very annoying to redeem – SurveyMini Review

Twice I have been standing at the checkout and attempted to redeem a coupon only to have it tell me “try again later” It’s very disappointing. I can’t figure out the randomness of points either. I can’t eat all the Krystal burgers I win or the “buy one get one” donuts. Sometimes if I actually have not been to a place it asks me about, I get 500 points. But a place I visited and submitted a survey, I only get 100 points. Go figure.
