How to derive two prices for a product?

Hello. How to make two prices for product cards displayed? That the price for a canvaswas indicated and price per set?
Example:
elporta.by/catalog/mezhkomnatnye-dveri/e...51-black-line-whitey

Hi,

You want to create a characteristic with two choices "За полотно" and "За комплект". Then, add that characteristic to your product, and create two variants, based on these two values, and in each variant, you can enter the price to be paid for that variant of the product.
Then, on the product page, based on what is selected, you get the corresponding price.

Thanks friend
