Does Not Ship To UK

[NorthernTravels]

Hi, Tonight I had a customer who bought an item, but it did not ship to UK, it was from Russia, but they did from China and a few others, So my question is, Is there an app to install so customers can get a warning before checkout to say shipping unavailable to UK please pick another country etc? or something on the lines, This would save me finding out when I go to AliExpress and realise that the customer's product is not available for them, simply because they never selected the right country for shipping, had to give the customer a refund straight away with an apology.
