The same thing is true today in Buffalo. Canadians are coming over the
border and shopping in the US. They strip down to their underwear on the
parking lot, and change into their new clothes. The old stuff is thrown out
the window on the way out of the parking lot. Some bring empty suitcases
and try to tell Canadian customs they're returning from a long trip.

And not just electronics. Years ago I know a young Brit who with
others would fly to the use on shopping excursions. They could fly
over, purchase their clothes, pick up as much extra as allowed and
pretty much pay for their own new clothes AND the round trip airline
ticket.
