Please explain you mean by “to go”? Or do you mean they are to be mailed from the USA to Europe?
Your post reminds me of two things: First, the Seinfeld episode where Kramer and Newman collect empty soda cans in NY City, where the refund value is 5 cents, with the idea of making a profit by delivering them to Michigan, where the refund value is 10 cents. That’s fiction of course. Second, and this one is non-fiction, in order to restore Ernest Hemmingway’s car, a 1959 Chrysler as I recall, located in Havana, the replacement parts had to be mailed from the USA to the UK, and from there, mailed back to Cuba. This was necessary b/c of import/export restrictions between the USA and Cuba, due to a long-standing political feud about which few if anybody outside of politics cares.
