Hey, anyone have a "definitive" answer about where I can ship adult DVDs to, from my web store?

I thought there was some subscription service I could get, where each quarter they'd mail me a database of all the "bad" zip codes in the USA, but I can't seem to find it.

I've tried culling information from other web sites, but they tend to erase entire states ("we can't ship to NV, OH, GA" etc) or even worse, they don't have the full info ("can't ship to parts of Florida"). I hate cutting out an entire state (though Utah may win, anyhow... heh).

thx
