With no set up costs, this is a free fundraising service where BT subsidise it so much the ONLY charges are 15p from debit card payments and 1.3% from credit card payments, charges directly charged by the credit card companies. Apart from this, the charities get all funds paid. With no monthly fee too, it makes it worth registering even if you are with one of the other similar services too.
