If/when the subscription amount changes the following pages need updating:

http://www.openvpms.org/yearly-openvpms-subscription-1-fte-vet

http://www.openvpms.org/admin/store/uc_discounts/list

Note that the discount needs to be set so that the subscription component is discounted by 50%, but not the development levy.  ie if the total T = S + L (where S is the subscription and L the devlopment levy) then the discount is (S/2)/T
