Ok, my mistake, it was advert of "start your own community" other option:
https://invisioncommunity.com/features/commerce/
But still, I don't think we need Commerce. What is for exactly? I think commerce is rather for making shop or something like that, we don't need it, I just want to have Classifieds 🙂
And one other thing:
Integrates to Commerce, so you can choose a specific payment gateway, tax, fee and comission and use multi-currencies.
I wonder if it support some Polish payment stuff. In other case it will be useless in my country.
