[QUOTE]Under the Consumer Rights (Payment Surcharges) Regulations 2012 a supplier cannot charge you any more than the fee that they themselves incur for processing a payment made with a debit or credit card. For debit cards that is normally 20p per transaction and for credit cards 2% of the amount charged. If 20p is less than 3% of the parking charge that you paid then you should take it up with Edinburgh Airport and ask for a refund - I certainly would, not because of the small amount of money involved but on the principle of it and the fact that the airport's franchisee is acting illegally.[\QUOTE]
As you seem to know a thing or two can you say if this is why, for example Glasgow Taxis, charge a 'convenience fee' for credit cards? Does that make it legal?
