Does anyone know if there's a shop, either "live" or online, that sells items from other countries that are not necessarily available here?

My husband has to travel to America at least four times a year, and I always send him off with a shopping list. But I think he's getting really tired of packing things like cocktail sauce, Total breakfast cereal, and Joy dishwashing liquid into his luggage. And so far I haven't been able to convince him to buy me a Tofurkey, since he'd have to pack it in ice first.
