I probably don’t need one either and was thinking of getting rid of my one some months back, but i kept it on the basis, its €30 per annum with no further charges applied, if the balance is cleared promptly.
Bit it is true their use, has reduced substantially in recent years, but there remains some albeit quite limited situations, where they still remain convienient.
Some examples:
i can top up my Revolut directly from the credit card
I was charged over a grand of a pre- authorisation on car hire in Italy recently. If you have plenty of cash in your account then, a non issue.
Big ticket items, okay, these are rare, but buying a new sofa set, or a number of appliances, or a large payment for say a bathroom refurb, some long haul flights & hotels.
Some of these items could be 5 to 10k, so a credit card is handy in those situations, if you don’t have immediate access to that level of funds, but can get it, in a few weeks to avoid the excessively high credit card interest charges.
For the above items, which are i admit quite limited, i think €30 a year, is not bad value.
