Generally most consumers are aware of the cheaper retail prices of many consumerable goods outside of their own territory.
Do you really think so?
Go to any electronics store, find someone looking at a TV or DVD player, and ask them the precise price of that item in Japan. See if you can find a single person who can give you a correct answer.
A lot of people know that electronic equipment tends to cost loss in the Far East. UK car buyers tend to realise that prices are cheaper across mainland Europe etc.
Being aware that some areas may have cheaper prices for some products is a long way from knowing precisely what the difference in price is on the other side of the world. I bet the average Brit couldn't tell you the price of a Jaguar in the US without looking it up first.
