A couple? !!!!
Try developing categories system and approval system on your own and see how much it costs, i can assure you you would multiple the 78 euro at least by 10.

The Deluxe is another product anyway, since we plan different ways and paths for both of these products in the future.
I can assure you also that we are providing further support for the simple version.
