i prefer not to have to sign for the package for a few reasons. one, it would be much easier to deny i ever bought it and two, if im not home they will leave the package on the doorstep i wont have to go pick it up at the post office. i dont really care about resends, my guy has genius packaging that I dont think customs would ever catch on to.
Possesion is 9/10ths of the law. You dont think LE can watch your doorstep? Being tipped from customs that means they have already been in your package and have a search warrant ready. Have heard sometimes the cops can put a device in the package that tells them when it's been opened. Once you open it they storm your house search warrant in hand.
Like I said if the cops/DEA know there is gear in the package (and thats pretty much the only way anybody gets busted buying through the mail) it dont matter if you sign, dont sign whatever. At one point you must take possesion of the package. And they don't play that "Geee officer its not mine, I didnt know there was gear in there" game, like kids do.
Bad part is I wonder what happens to it if you cant claim it and your address is on there? Hey all in all you may get lucky and some PO employee will allow you to pick it up anyhow.
