Discount Codes for PF CHANGS

I apologize if there is already a thread about this, just wondering:

Anybody come across any discount codes, yet? I think I had one from racing in Seattle, but don't know what I did with it.

Who else is planning to run this year. I'm in for the half and thinking about doing the full at Lost Dutchman.

Anyways if anyone has a discount code they want to pass along it would be appreciated
