With deals that include shipping at $20, $40 per item, I'm not surprised US sellers are becoming "reluctant" to sell to the UK and Europe. The negative feedback on shipping is too damaging. I just paid nigh on $20 to have a very slim newspaper shipped to me in the Netherlands.
I queried the seller and they said it'd be sent in LP packaging so that it was extra secure. All I got for that 20 bucks was literally that - an LP carton and a newspaper. There was no actual protection whatsoever. Increasingly sellers are ripping buyers off through extortionate p&p.
Craig Moerer and plenty of others can still ship 45s to Europe at under 10 bucks. Why then do others have to charge double, triple that? Enough is enough - and I think rip-off US sellers are getting the message.
Sadly though it's ultimately to our own detriment!
