Since the PC section discount is only one aspect of being a PC member - I'm not so bothered when new stuff doesn't show up all that often. I also always check for new things in the Premiere & Loft section to buy at the additional discount allowed by being a PC member - as well as looking in the free area & free archive.
I seem to remember that items sold in the PC were going to be (some) DAZ creations as well as certain independent creators who have an agreement with DAZ to have their items sold in the PC. Some of the lack of new items that you want, Khyrs, may be due to not many artists wanting to trade off few high priced sales for more low priced sales.
