Woocommerce creates the page you linked to using what I would call unconventional layout. On one hand, they use a more or less standard .entry-summary class used by many themes, but they use it it an uncoventional order with uncoventional nesting.
I will start a topic in Weaver and Plugin Interaction called Woocommerce Hints that can be used over time to add little tweaks that might be help Woocommerce layout.
But as it stands now, Weaver Xtreme supports Woocommerce at a fairly basic level, providing the proper sidebar and display page template that Woocommerce needs to function properly. Providing custom styling is really beyond the scope of the support we can provide. This is partly because Woocommerce is a huge plugin which requires a steep learning curve, and we simply do not have the resources to learn all about individual plugins, even one as widely used as Woo.
