Thank you for expressing your interest in acquiring a WordPress Toolkit Deluxe license! At this time we do not have an official ETA, however, I encourage you to check out our cPanel Newsroom | cPanel, Inc. for updates on the upcoming license information.
Since you have no ETA, the least you could do is offer a free trial for the Deluxe version of the software until you do instead of reminding the users the opinion they want requires an upgrade, then sending them to a page that has no option to purchase said options.
To be clear, I want to pay, but you released software without the ability to pay or unlock the deluxe versions. This seems counter-intuitive for a business, especially since you are porting WordPress Toolkit over from Plesk Buy Plesk - Plesk.
