Backcountry Discovery Routes review for Advanced Shipping Rules

After using it for a few months, App seems to work well. We were forced into the middle-tier pay plan since our orders went above a certain limit. Only 3-stars because after 2 emails and a voice mail over 10 days of trying to get support, I have yet to get an answer back. If you are reading your reviews, please respond to support emails! UPDATE: Looks like my email was going to spam, and they emailed me back immediately after seeing this review.
