Today I got an email from the same person at Amazon asking why I hadn’t responded to the PSP offer (Pallet Shipping Program) email they sent me a week ago. Well I did respond and profanities were probably removed from that too. 
Our total restock limit for the EU is less than a pallet. What are we supposed to do? Let everything sell out and then send 3/4 of a pallet?
It took me two months to find a solution for getting our goods back into PAN EU. When I finally got there I was so relieved. We send a few parcels in March. As confidence grew I started sending 12 consignments at a time. 432 products, all small packets, once a week. Slowly building stock back up and taking the pressure off MFN.
The restock limit is a constantly changing, evil entity.
We manufacture our own products. Last week we had 477 left on our restock limit so I went for it. We made the products, specifically for the EU market. Many are novelty products, in the German language so not suitable for UK sales. Then, as I went to prepare the shipments, our restock limits dropped again.
I had to abandon sending any more stock into PAN EU until the restock limits rose a few days later. So many items were out of stock in PAN EU, our MFN sales went bonkers right when IOSS kicked in and it took a while to know what codes to use in C&D.
This is not why I signed up for PAN EU and huge costs in money, time and effort.
