[Solved]Product Characteristics with price?

In my pizza site I would like to have be able to choose a pizza with a base price (lets say CHF 20) and have the choice between 20cm and 30cm, where the 30cm version adds CHF 10 to the base price.

I added the characteristics but cannot add prices.

How can I do this?

Hi,

When you add the characteristic in your product page simply click on the button "manage variants" above the characteristic listing field.
You will then be able to edit each variant and assign them a unique price, image, description and so on...

Right. I think I got it. Thanks
