I always give the correct country. However if they are trying to be more clever I give a unique "faked name" to each site that demands a Postal address. (In this manner I can get an idea of who's sold my name and addy to all those marketers) While this might sound just a little anal to some of you, I get to boycott the products of the really poor sites.

Sheesh that looks anal even to me.
