How to set up an affiliate product in WooCommerce store?

Hi
What is the proper way of setting up an affiliate product in WooCommerce store?

I have added the Blocksy PRO affiliate product to my WooCommerce store.
In the product settings, in the General tab, in the Product URL field, I have pasted the affiliate link. So far, everything is understandable.

But what should I do with the Regular price field?

There is no point in entering a price here:
First, Blocksy PRO prices can fluctuate and I would have to check them often.
Secondly, in fact, the affiliate link redirects the user to a page where he has to choose one of several available options: lifetime purchase or annual payments. Additionally, they can buy a personal, professional or agency package.

So should I leave the price field blank and enter prices in the product description?
Or maybe we don’t provide a prices for affiliate products (?). The user simply finds out about them after clicking the Buy now button.

regards,
Grzegorz
