Great post, Sarah! PHPStorm reached out to us several months ago, offerring any contributors to WP eCommerce a free license to PHPStorm.

A lot of our contributors have been taking advantage of that and absolutely loving PHPStorm.

Now that the final release is out, I'll likely be switching over myself. We're really grateful that PHPStorm is devoted to contributing back to the open source community in this way. Shameless plug: If you're looking to get a free license to PHPStorm - we happily welcome new contributors to WP eCommerce over on Github :)
