What are you trying to achieve:
Hello, I would like to hide a page, (in my case the pricing plans page) from members who already bought a plan (and keep it visible for the non paying members and non-members). I didn’t find a post or anything on the internet about this so I am asking here if anyone knows a way 
Never really touched PricingPlans, but how does it work?
You create several pricing Plans…
https://www.wix.com/velo/reference/wix-pricing-plans-backend/createplan
A member makes an ORDER TO A SPECIFIC PLAN…
a) offlineOrder —> https://www.wix.com/velo/reference/wix-pricing-plans-v2/orders/createofflineorder
b) markAsPaid - Velo API Reference - Wix.com
Let’s say the user made his order and payed —> what will change the stats of order for this user…
Reading the orders-info → memberGetOrder - Velo API Reference - Wix.com
Or listing all ORDERS first… → https://www.wix.com/velo/reference/wix-pricing-plans-backend/orders/listorders
So check all given APIs first.
Once your code can recognize who paid a plan and who not, your next step will be to hide the page from customer.
The pages they will reach surely through a menu, in this case you can manupulate the menu…—> menuItems - Velo API Reference - Wix.com
Or you use a → direct REDIRECTION to another page.
