I live in a small EU country, we have euros, mastercard/visa based credit cards, we're in the schengen, and somehow even within EU some companies won't ship to us (while shipping to eg 18. other EU countries). That includes amazon sellers! If something is eg 100eur cheaper in germany than here, I'd use (and did use a couple of times) one of the reshipping companies, that take the package I ordered and for a fee, ship it to my country. Same for US, a lot of stores don't ship outside of US, some due to not wanting to deal with that, some due to more practical reasons (wrong electric plug, etc., don't want to deal with customers complaining), and well.. use a reshipper for that too.
