Hi Asta,
The shipping modules that are included with WooCommerce are based on a GLOBAL cart rate. So if you have 2 vendors products in your shopping cart, it wont do it right and it will not assign the vendors the shipping cost. This is the reason we have to write our own shipping module.
We’re almost done with 1.0.2’s release, we have found a layout system that works and are recoding it and the javascript right now. We expect to have it released before the weekend is over. Truly sorry for the delays, we didnt expect to have to rewrite all the shops and dashboard layouts in the first release because of theme issues for half of our buyers.
Soon as that’s done, we begin on 1.1.0 which will have the shipping module. It won’t be long, but it is probably still 10-14 days out.
