When the ICRM Single Discount setting is enabled we would like the items that are discounted on the transaction to only apply the best available discount for the customer.
Example: 10% Gym member discount is available and 25% member discount is available the 25% member discount would be added to the transaction instead of 10% Gym member discount
in addition the discount would only need to be applied to products that are linked to the discount and not the transaction.
Example: Fish & Chips Friday for £15 Reward isn't further effected by the 25% member discount causing the item to be discounted twice.
