Welcome to the Jungle!!!
As far as an online seller to the UK, i dunno if any one will have your answer here. An easier way to find out is hit up the normal sites, and just email them.
try:
www.cigarsinternational.com
www.taboocigars.com
www.cigarbid.com
theres a whole bunch of em w/ a sticky somewhere around here. Id try CI & Taboo first, Robb gives us great deals at Taboo, just about every other day. You might be able to pm on here and find out to!
Happy hunting & good luck!
