Shopify Marketplace Connect

not very good,
not all the categories of Amazon is in this app, so when u send date from shopify to Amazon you are not able to select correct category and then Amazon won't allow u to change it.
Customer care support is on and off, some time u get a good person some times totally waste of time.
only reason I started using it with the thought that its by Shopify but not looking for other apps to select and that may cost me a lot of time in setup.
