On my multisite network, I'd like to be able to charge using pro sites something like this;
level 1 1-100 listings in their marketpress store
level 2 101-200 listings in their marketpress store
level 3 201-300 and so on...
Can anyone advise how this can be achieved please? I don't mean how many gb's of data they can store etc, I need to limit actual amounts of products able to be listed.
