AMEX Gift Card
Do you have an American Express AMEX Gift Card instead of a credit card or charge card? If you are lucky enough to have been given a gift card then you are probably not too sure where you can use it. The good news is that it is widely accepted, and only has a few extra restrictions.
Here's the advice given directly from American Express AMEX:
"The American Express Gift Card is accepted in the UK where American Express Cards are welcome. Please note that exclusions apply: the Gift Card cannot be used at ATMs, gambling establishments, cruise lines, payment and money transfer providers, customer activated terminals e.g., unattended ticket machines or for purposes of guaranteeing payment of future purchases."
