In Paris back in 2000 a bottle of Grand Marnier was about 50FF or $8.00 Here in the USA right now it is $35, after all the excise taxes etc.
The drop of the dollar would make that 12$ add inflation that would make it 24$
I pay now 16 Euro for Grand Marnier which I use to cook lobster a l'amoricaine . So our figures match Europe side
Every importer takes 30% gain so your 35$ is only 3$ for the retail seller .
If transport was not so scandalously expensive you could have 6 bottles shipped to you by boat
and do the custom declaration yourself in theory saving large part of the 30% but the importer likely
ships it by the container at a few dollars cost per bottle and you would have to pay a lot more .
( The French taxes of like 21% are refunded and chances are very high your excise and american taxes are less so the importer wins on the excercise too)
I buy cherries on 100% alcohol directly from the factory in France . The cherries are per carton of 6 like 50 Euro and the shipping is like 40 Euro per six
No supermarket sells them in Belgium and I got addicted to the taste . Lucky no customs exist anymore in the EU
