Here's just one small tip, of many: If you're buying antiquities from a war-torn region, and the seller tells you to instead wire the money to eight different people, none of whom is him, it's possible that this transaction is not on the up and up.
Oh, and a second tip: if you're legally exporting things you think you bought lawfully, don't disguise them as something else.
But yeah... I get it, you're not really interested in the truth of the matter. You're just trying to pretend that you're smart or some crap like that.
