Allen Designs Studio review for Advanced Shipping Rules

We have two sites with multiple product groups, fulfillment locations, as well as domestic and international shipping destinations. The rules we needed were fairly complex both to build and to explain. Not only did the app accomplish what we were hoping, the support from Molly included multiple back and forth email replies with extensive documentation, patience, and even videos showing me how to set up the more complicated aspects. Great app, even greater customer support. Highly recommend.
