It is being shipped for free from Tokyo and is or soon will be tied to my MtGox account.
The coupon code can be given to anyone for them to order it for free.
If you have a coupon code, log into your MtGox account, then go to security center, then under the Yubikey menu click "add new" and there is where you order it for about $30 but below that is where you submit the coupon code which changes it to free with free shipping.
That explained it rather nicely - thanks.
I'm sure I could sell it for more then 0.1 BTC if I wasnt limited by the stupid limits of this forum or had more time, but can't be arsed.
Thanks to grue and doubledave for additional explanations.
You should not be sorry - there's too many scammers here, so it's important to stay vigilant. Until this was cleared up, I somehow wondered if there was some kind of nefarious scheme to run away with the funds of other people. Since you didn't explain it quite well, and a MtGox yubikey code is not exactly something you see traded every day. In the future, adding as much information as possible to a post is not a bad idea.
