After being informed by support reps that condition notes are only available for Amazon.com orders (Found Here), I was directed to post about adding this feature as an enhancement.
My company is a renewed seller on Amazon, and Amazon recently made changes to the renewed program where you can choose different conditions for renewed items. The condition notes coming from the Amazon Store connection in shipstation help our pickers/shippers know exactly which condition of renewed items they need to pick/ship, without having to dig that information out of the item SKU.
This feature would be very beneficial for any renewed sellers on Amazon who happen to sell internationally through the Amazon sales channel. This feature should be enabled for all international Amazon channels.
