"Card payment surcharges Consumers who pay by cash are effectively subsidising credit-card users. Stores pay a fee to the credit-card company whenever they accept a credit-card payment, but they charge the same price to all customers regardless of the payment method used. Businesses can now add a surcharge for those paying by credit card. But the surcharge shouldn’t be any higher than what the retailer pays to the credit-card company. And the basic price for a product should be reduced when a retailer introduces a surcharge on credit-card payments."
Oh well, I will enjoy an exercise walk to the post office and pay it there, does make me think less of a company when they do this though.
But handling cash isn't free.
Also, the Post Office charges Vodafone for handling their payments, so maybe they will attach a levy there as well.
