Had some fun talking to Amazon support about system issue where I am unable to recall my inventory to NI post code, here is the reply:
_Hello from Amazon Selling Partner Support, _
I understand your concern regarding error when creating removal order.
_Please note that you can remove the units by creating a removal for stock via flat file. _
_The reason why the postcode is not considered valid by Amazon is that the seller is selecting GB (Great Britain) as country. The difference between UK and GB is that GB does not include Northern Ireland. _
Please note that we cannot ship the removal orders to Northern Ireland.
You need to create removal order for the local address in UK.
What do you think about that? I am speechless!!!
