Members can purchase any product you make available on the Members Portal. They can access the products listing by clicking the Products and Services icon in the navigation menu.
From there they can choose to purchase products and services as a one-off item or to add the product to your plan as a recurring item. All you need to do to add a product to your basket is select a quantity.
Once you are ready to check out, you can then either click on Add to basket to reach the checkout page. You can enter a discount code and then click Continue to pay for your purchases through your preferred payment method.
