How to link the value of a custom field (ACF) of one page to hundreds of others to simplify the process of editing values?

Question

Taxonomy

There is a product "Boots", an arbitrary field "price".
But the product "felt boots" has many pages, "felt boots with delivery", "fashionable boots" and others. But the product is one, the price is one.
How do we display the price on different pages, but I edit it only once. If there are 100 pages about these felt boots, then this is 100 changes to carry out.
And I want to change the price only in one place. How to be?

Answer 1

It seems to me more logical to make one product "boots" with a price, and all these options are either a variant product (that is, variations) or a taxonomy.

Answer 2

You have a separate post type - products, where the price.
And there is a separate type of records - where "boots with delivery" and so on.
Here you make a connection between them, from the second you refer to the first. ACF has a whole field type for this - relation
