Be careful on that Tamiya site. My Amex started getting hit daily after I bought a model there on-line. Hadn't used it anywhere else in a while - so pretty sure that's where it was grabbed. I received a call from an Oriental lady I could barely understand asking me to confirm my $1000 gift certificate. That clued me in to start looking into it and sure enough, when I called Amex, somebody had beeen hitting my card hard! Lusckily, I wasn't held responsible, as it was obvious fraud.
