Changing the price of variant products with Mass Actions

Hi,

You can create a mass action with a filter on the product_name column, and an action "update the values" on the price_value column.
A product mass action will, by default, target both variants and products.
So if your filter on the product_name is restrictive enough to concern only variants, then you don't need another filter. Otherwise, if you have overlap with the products, you can add a second filter on the product_type column being equal to "variant" in order to target variants only.
