WC_Product_Variable_Data_Store_CPT::read_price_data() WC 3.0.0

Get an array of all sale and regular prices from all variations. This is used for example when displaying the price range at variable product level or seeing if the variable product is on sale.

Can be filtered by plugins which modify costs, but otherwise will include the raw meta costs unlike get_price() which runs costs through the woocommerce_get_price filter. This is to ensure modified prices are not cached, unless intended.
