Hello all.
I'm hoping to shed some light on the confusion here. We are the original developers of the majority of WooCommerce shipping plugins that we sold via their store.
We've transition our extensions and support from WooThemes to our own store which can be found at http://www.extensionworks.com.
@WillieO - If you are an existing Woo customer, like @babbsela, we'll be happy to provide updates and support for our products moving forward. Just send us your details to sales [at] extension works dot com.
@dax702 - I believe this will have no effect on our code as we request the rates, either standard or commercial via their API.
@Gampopa - feel free to send the details of the issue you have mentioned and we'll take a look at it.
If you don't get any joy, I'm one of the owners of the business, so please feel free to drop me an email anytime to shawn [at] extension works dot com
