I'm going to Switzerland next month for a couple of weeks and would like to bring some European aftershaves and colognes back to the U.S.A. Anything I purchase would go into my checked baggage. I'm wondering if there are any restrictions on the quantity of such alcohol-based items that I can pack? Since I only get over there every 2-3 years, I'd like to stock up, but I'd hate to spend the money only to have most of my purchases confiscated at the Zurich airport!
