I live in Northern Ireland. I have today tried to purchase 3 separate items from companies in the EU and one in the mainland.
They all state they don’t deliver to Northern Ireland because of Brexit
How has this happened where there is a border in the Irish Sea.
I can have parcels delivered to Ireland - no problem. Mainland UK - no problem
Northern Ireland - nope.
We are still part of the UK nothing has changed!!!
I’m so pissed off
I would expect additional charges maybe if the parcel has to be delivered through UK and on to us. I did not expect that years later this would still be an issue
No wonder the Northern Ireland government has collapsed! I fully support the collapse, maybe Westminster will finally take some action, although I doubt it 
Fuck you Brexit. Send me my parcel
