Well, I just got off the phone with DAZ.

I was told that the reason my coupon wasn't applied is because everyone must "wait" at least 24 hours after joining ArtZone (as a "new member") before placing the order for the coupon to appear. 

I still had to pay $19.95. Which is still more than fair and I'm happy.

I asked about the Bryce 5.5 $0 deal...

I was told that it's a "glitch in the system" and it's not supposed to be that way for PC members!

Now that they're open, it will be fixed soon.
