I don’t expect developed stacks to be free (€0,-), but it is misleading when on the Rapidweaver store states ‘Get Go CMS Unlimited - FREE’ and on clicking that button end up in the @yabdab store to find out it is $149,-.
On the Rapidweaver community website I think and find developers should state the correct price. Just my opinion.
Developers are by themselves responsible for the information displayed on the rw community site.
But: You have limited functionality there. For example, it is just not possible to mention that one product is only available in a bundle. Or, that there is a free demo without saving capabilities.
