www.mmosupplies.com has them for 20.85.

My first account took a few hours because they had an automated call back/pin thing to verify I was real. Second and third account were were sent in under and hour. My last bc purchase though took 1 day!!! - Not sure why that was and luckily I didnt need it right then to play or I would have been a little perturbed. All in all I've ordered about 10 keys and will continue to use them.

FYI
