Monthly package option needs a "confirm" stage

[Sir Noel]

So I got caught out yesterday when I received an email informing me I had purchased a months video subscription to Glam Porn!
I am sure support will cancel this (I emailed back immediately) but the issue is that there is no confirm stage to the purchase. It is easy, especially on a mobile device to mis click on the wrong thing on screen (which is what must have happened) when simply watching a trailer or browsing scenes.
