@rgregory - Yes, I agree that this type of plugin is something you use to make money and, therefore, is not as price-sensitive as plugins in other categories. It would still, however, be a good idea for potential users to look past the FREE and acquaint themselves with the ultimate cost - for instance, realistically, even the simplest online store serving the European market is going to need the VAT Exemption add-on.

The importance of fully acquainting yourself with pricing structures before investing your time applies to any complex product.

With regard to support, I noted in the discussion on the Woo blog about pricing, that the cost of providing support was a major consideration in their decision to break from their previous "all-you-can-eat" approach. This suggests that they intend to do a good job of supporting Woocommerce users.
