Shagg orders from them every two months for us, a fair amount I might add, but a few months ago he got an e-mail from them stating that they no longer accept PayPal payments from Canada because some smart-ass from somewhere in the country ordered an airsoft M203 grenade launcher from them and it got siezed, then returned to them. Caused a crapload of b/s for them, since then they only accept wire transfers from Canada to pay for the order. Only quoting Shagg's expereince, he's posted the replies on our forum, but it would be good for other people who order from there to state their cases as well.
EDIT: Ok, I now see that you are in the US, I have no idea what is going on in your case. Sorry.
