Hi @modeltheme! I’ve just spoken to the team managing the WP sales page. They confirmed a few details, but also stressed that the page is still in active testing and only displayed on the site navigation for a subset of ThemeForest visitors.
Content on the WordPress Sale page is regularly added to, with some items added to and/or removed from the list. The selection process is still random from items that meet the “promotional pricing” criteria outlined here. It’s important to note that simply listing at a promotional price does not guarantee inclusion on the sales page: eligible items go into a pool that is used to select what is shown.
I did a few spot checks and couldn’t find items that were still listed as “on sale” with regular item pricing - I assume the ones you mention were removed before I looked. If an item on the Sales page returns to normal pricing, it should automatically be removed from the page. Sales listings can also be manually pulled down: if you see any other cases where items shouldn’t remain on the page, please open a support ticket to let our Marketing team know.
EDIT: Just confirmed that a bug was causing some “off-sale” items to remain on the page, despite being flagged for removal. That has just been fixed, so items should automatically leave the WordPress Sale page once prices are raised.
