Hi there When you go on the site to buy a one-off purchase (not subscription) it says it will be £69 (or £79 for annual sub), but when I try to purchase, it switches to the annual one without warning and the one off purchase doesn't appear. I tried the same thing on another browser and the same thing happened again, but this time it gives the option to change back to one off purchase, but the price goes up to £79.99 - what is going on?
