@gsuberland actual DHL case many years ago - I ordered Propellerheads' Reason from Sweden. They have (or had) the wonderful policy that EVERYONE pays the same price, and they then pay off of that the tax which is different depending on country. So I paid my $129 and about 19.34% of that would go to the Icelandic tax office. They sent this with DHL and pre-paid the tax and customs fees and everything.
DHL *STILL* tried to bill me for said fees AND a service fee!
They're sewage rats, at best!
