Well, I've just had official confirmation that the forward shipping company I use to get goods from the UK to me in Bulgaria have now ceased trading in the UK because of Brexit.
I've been using them for over 5 years and I've shipped hundreds of items, from cheap eBay rubbish to musical instruments and even expensive computer parts, bank cards, and official documents, without a single problem. By far the best and most reliable courier service I have ever used, and they're now out of business, and all their UK warehouse staff and drivers out of a job. But I bet they're buzzing about their blue passports.
