I would have agreed until recently, but they've actually sent out several 10% off deals in the past few months. I'm guessing the economic slowdown has affected them too.
The ones I've gotten have been for one time use, and have been tied to the source code on my catalog, but not to my name specifically. Unfortunately I've already promised my current one to someone.
But if no one here has an extra, you might want to try e-bay. Of course some folks ask outrageous amounts for them, but I've seen a few reasonable BIN auctions too. Given PB prices, paying a few dollars to save 10% off your entire purchase might not be a bad deal.
Good Luck!
