While it may sound too good to be true, I have attached the link to their offer site.  Seems that if you buy a set from an authorized dealer before 12/31/2009 that you are able to upgrade (FOR FREE) to any new set produced between 1/01/2010 and 12/31/2011. 

So if you're in the market for new irons before the end of the year, you may want to look into this and see if they have a set that suits you.

I play the CG Tour blades, but am in no way affiliated with theses guys.  Just passing the info along.
