Woocommerce text domain

It’s “woocommerce”.

If you’re having problems getting the right combination of original string & domain, then you’ll need to dig out the original string in the plugin code – check the FAQ (https://ww.wp.xz.cn/plugins/say-what/faq/) or this article for some examples of what you’re looking for.

Alternatively, the Pro version of the plugin provides a String Discovery mode which means you can search for strings on your site via autocomplete suggestions.

Hope that helps.
