category prices

The ability to define prices globally or on a per category basis is built in already. You can find that in the “Pricing” tab of the plugin backend, see https://ps.w.org/laterpay/assets/screenshot-4.png?rev=999866

All you are doing on the Add / Edit Post page is to select the category of which the post should take its price.

Does that answer your question or did you think of something different?

Yes I know, I created such a category price. But I have to edit my existing posts within that category one by one and change them from individual to category price.

It only seem to work for new posts. Because when I create a new post with that paywall category the price is adjusted automatically.

If you have a lot of posts, it would be easier to adopt the category price by bulk automatically.
