For example, none of the Cymbidium, prae, MDD, STZ, Ken-Gilliand offerings of the Poser/ V4 series are not showing up with any discount. Well, one or two have 30% off, but  mostly they have zero discount in the sale window.

When I click through on the item, however, so far most of them are showing up at 65% off on the item itself. At the moment I don't know if it follows through to check-out.

example:

https://www.renderosity.com/marketplace/products/84890/natsuki

https://www.renderosity.com/marketplace/products/82115/stz-footwear-collection-for-v4

https://www.renderosity.com/marketplace/products/146127/songbird-remix-optics

I'm afraid I don't understand what the problem is.   For example, cymbidium has 9 products in this sale.   On the sales even page, clicking on the vendors will take you to the products that vendor has in this sale.  https://www.renderosity.com/marketplace/browse?sb=newest&vendors=449344&sales%20events=1383&results_per_page=60

All 9 of those products have the 65% Prime discount.  

Where exactly can't you see the 65% discount?

It did not initially show up on the main screens in the early hours.  I had a similar problem. When I came back it had corrected itself.
