I have a new installation of WooCommerce 2.0.11 (originally 2.0.10 before upgrade today) and WordPress 3.5.1, using the latest versions of both (as of 13 June 2013).
I only fill in the Regular Price on each product, but on the front page it shows that all products are For Sale, at the same price as the regular Price.

I've tried a fix mentioned in the forums - switching to Configurable Product and back to Simple Product - but nothing seems to fix it.
