I need to ask the not so obvious. Ship what?
Scotch from stores around the USA? Scotch from stores in the UK and Europe?
If you are looking in the USA i would either try http://www.sameswine.com
both stores are located in Illinois. They ship to approx 44 states if I recall.
You can ship product in from the UK, however, you need to get a special permit from the ATTB (formerly the ATF). It would be cheaper and easier in most cases to buy a plane ticket to the UK and buy your booze and fly home. You can get a special case made to hold your booze and place it into checked baggage.
