There's certainly a business opportunity for supermarkets in Carlisle and Berwick upon Tweed not to mention all the small shops in other border towns. I'm sure we'll see the return of the white van full of booze trawling the back streets of the central belt.
The best comment I've heard so far was the old Russian joke;
"Father not vodka has gone up in price will you drink less?"
"No son, you'll eat less"
