Heritage Steel review for Shipr for Amazon FBA / MCF

After trying a number of different apps to automate FBA shipping of my Amazon orders, this app has proven the most flexible, reliable and affordable. The dev team is very responsive and helpful. A couple of great features that most others don't have: - Uploads tracking information by line item rather than by the entire order. This is CRITICAL when your orders often get shipped out of multiple fulfillment centers and therefore have multiple tracking numbers. - Customizable shipping out of FBA warehouse vs your own warehouse based on inventory levels. This helped us out a lot.
