Clarify fees for producers upgrading to a shopfront

When a producer wants to upgrade from being a producer only to a producer with a shopfont they get the screen below which doesn’t explain the full fees payable. Please can we change ‘FREE TRIAL THEN 2.0% OF SALES ONCE TURNOVER EXCEEDS £420 PER MONTH’ to ‘6 MONTH FREE TRIAL THEN £20-£40 PER YEAR PLUS 2-4% OF SALES ONCE TURNOVER EXCEEDS £420 PER MONTH’

This will now be replaced by details of the OFN platform cooperative system in which all users will pay according to 1) their use of the service and 2) their ability to pay
