Hi Alexander. Great snippet! Thanks.
I can't figure it out to use the price of a variant, the snippet grabs the lower price of the range.
Can you help me?
Thanks.

Is this supposed to work for variable products? It seems to only grab the product base price.

Hi Alex.... I´m using it but I can´t see the total price on the product page.
What am I doing wrong?

maybe you can take a look: https://cepadevinos.com/producto/zuccardi-blanc-de-blancs/
