A few of the things I sell I get from a small number of traders on Aliexpress - the price is fine and the deliver simple and I can repeat orders in smaller quantities simply. The products cost me around £150 each, and I'll buy 4 at a time. I've sold a few this week so topped up the stock - everything normal. I get a message asking me to cancel the order as they cannot supply, which I did and I'll get the refund shortly I think. However, I've discovered they are still selling them (admittedly for a few pounds more) and have alternative models too - so I asked why they'd cancelled, as they clearly have lots of stock available. It seems the stock is actually in Poland, and the Polish agent has decided it's too much grief sending things to the UK. Anywhere else in Europe is fine, but not here! I can buy from them Chinese stock, but the shipping charges are now over $35 because they're heavy and bulky. Sending a container to Poland and shipping from there is cheapest for them for Europe, so they cannot sell to me any longer with free shipping. This Brexit thing is becoming annoying now, even though I actually voted for it, thinking for me, it would have advantages. The hidden disadvantages are now making me really regret it!
