Stackable: Combined Discounts

This app has changed the way we do business. Each sale campaign accrued a lot of abandoned carts because we were unable to offer free shipping with our sales. Not any more!! We are really pleased with our early bird sales so far and we hope to see fewer customer comments about this now that we've added Stackable. I would also like to mention the awesome customer service. Many apps are slow to reply, but these guys are speedy & provide excellent & informative replies. I give them a 9/10 for this app. Waiting on multiple free shipping codes to give a 10 rating.
