VAT

[jpendle]

As @njee20 says once the UK has left the EU then anyone purchasing from the remaining EU countries will likely be able to buy VAT free, so if VAT is 20% (1/5) then you get 16.33% (1/6) off the listed price.

At this point it is up to the UK Government of the day what happens next. But probably, if there is no deal, then you'll get charged VAT (at 20%) plus whatever import duties are liable under WTO rules, plus a handling charge by the relevant carrier. If a deal is done you might get lucky and be able to buy at list price plus postage.

US suppliers only add sales tax if they are shipping to or selling in their home state and US prices NEVER include sales tax, although as Amazon have wiped out US sales tax revenues because of this loophole the laws are changing over here, but that shouldn't affect international shipments from the US.

As an aside, sales taxes are levied by the state, county, and city, so I can buy a jug of milk from the same supermarket in the 4 different towns near me and not pay the same price in any of them
