Its been a while since i sold one on discogs and ebay, but well packaged i was charging €15 to the UK. Rates have probably gone up since then, and they are higher for mainland Europe. Big issue now, is sending to the UK will incur duty + vat, and discogs will automatically apply these, so watch that. If one is buying just 1 vinyl, say on ebay or discogs, for say €40, the duty, vat & postage, is now adding about €30 to the cost, making it all cost prohibitive, for all but rarer items.
