My card has already been charged £1.00 or $1.00, or equivalent in my local currency

When you sign up for a subscription, our payment provider Stripe needs to verify that your card is valid. To do this, sometimes they will issue and then automatically reverse either a £0 or £1 authorisation to verify that the card is valid and able to be charged. This authorisation will be reversed within a day or two, and should drop off your statement shortly.
