I am one of those who asked such a question and was closed down (http://wordpress.stackexchange.com/questions/52236/using-woocommerce-with-hidden-priceshttps://wordpress.stackexchange.com/questions/52236/using-woocommerce-with-hidden-prices)
You'd think I'd be against this practice, but I actually found it sobering... indeed commercial themes should provide this support for themselves, and we, as clients, should encourage and demand it.
I do think, that big products (i.e. major frameworks and super popular plugins) should be considered for answering as they are used by a huge number of users.
For example in my original question above, If I would have changed the question to be about WooCommerce plugin, and requested a technique to customize the default price output (instead of being super specific to the (free) theme and specific field), I think it could have been of interest.
(In this specific case the answer is clear and support by plugin provider exists - so a simple link could have been the answer, but I'm just trying to explain my point).
Thanks to all the mods, you do superb work!
