I have bought many things from UK and EU companies. I have purchased the most from St Kilda Kilts, especially the clearance section of their website. The companies I have purchased from have been extremely pleasant to do business with. I only had 1 issue out of many purchases, and it was handled to satisfaction in less than 24 hours!
Shipping of goods once ready was quick! I have gotten orders from Scotland faster than from California at times...

I even got a custom dress jacket made to measure from China and recieved in less than 1 month including delivery! It fit surprisingly well beyond expectations!

Never had any customs issues, other than holiday delays through NY customs.

I am located on the Treasure coast of Florida.

YMMV..
