Remember that for us europeans (and for me, italian, in particular), the
STRONG euro is a great attractive.
We can buy US stuff at a VERY low price, consider that in Europe the prices
for the same stuff are still very high.
You all know that, like with gas/petrol, if the price lowers, not always the
final price is lowered for the buyer...
Through Ebay we find a lot of nice stuff at a reasonable price, and we don't
always know all the US online shops, or many of us cannot communicate in
english, and therefore Ebay is attractive.
Furthermore, soemtimes small parts in a padded envelope pass the customs
without an added VAT expense, while buying from shops requires express
couriers and almost always customs blocks.
Just my 2 cents...
