If you have a bunch of items showing up in your stranded inventory check and see if they are in the MDT2 warehouse.
Apparently Amazon has been sending inventory there prior to it opening later this week. I’ve got about 100 pairs of shoes sitting there collecting dust.
If you have stranded inventory that you want to check you can do so by using the “Daily Inventory History” report, accessible from seller central.
Reports -> Fulfillment -> Daily Inventory History
Based on conversations with some of the sellers in the Ninja mastermind group this appears to be pretty standard procedure when Amazon opens a new warehouse.
Do you have inventory that is affected? Have you run into this in the past?
