WunderZap review for Amazon MCF by ByteStand
July 31, 2019
I used this app without problems for a couple months. I woke up today to find that it said there were no rates available for my market, and that customers had been coming to the site for 14 hours without the ability to place an order, due to the shipping methods being broken from this app. I instantly deleted them and will never be using them again.

Unfortunately you ran out of FBA inventory. When a shop runs out of inventory Amazon no longer returns rates. The moral of this story is to ensure you do not run out of inventory as our other 800+ customers never had any issues.
