Raw Energy Tools review for ADU: Automatic Discounts

This app is fabulous and my clients love the discount being automatically applied. One concern I have found is it doesn't always add the discount even if the cart total warrants it. I've had this happen 3 times already and after ensuring everything is still active on both the app and the coupon area, it seems to be an app mishap? I emailed the support and was referred to make an account and ask my question on some blog feed. Didn't like that at all and because I could never figure out where to post for help, I never have gotten to the bottom of why this happens. Would give this a 5 star rating if it weren't for these two hiccups.
