接著，不可能一筆一筆去設規格品的價格，還好 WooCommerce 很貼心提供批次更新的功能：
Apply the price of a WooCommerce product variation to all variations of the same product
UPDATE: As it turns out, WooCommerce has added built-in support for the bulk editing of variations. While editing your product, after having added one or more variations, the “Add Variation” drop-down at the top of the Variations tab also includes a number of bulk edit options; you can set both regular and sale prices or modify either, increasing or decreasing by a percentage or set amount, for example.
Assuming you’re not using a very old version of WooCommerce, you can use the above and ignore the rest of this article.
