Hi i would like to ask if is posible to use k2 as my categories and items viewer and to use as well Virtue Mart to sell the products, i tryed K2 store but is incomplete and many thinks are missing. Or any ideas of how k2 can be an e-shop, info me plz coz i really love K2 and i dont wont to change in VM only.

There is K2/Tienda integration plugin in development: community.getk2.org/profiles/blogs/k2-integration-with-tienda-a

But I don't know, when will it be released. Also Tienda Enterprise Version is more powerful then Community Version which is free.

Maybe you could also take a look at VM snapshot plugin which you could use inside K2 items?
