I am on the verge of subscribing to Discovery Plus, for £6.99 per month, please, does anyone know do they class a month as a calendar month or 30 days from the day you sign? The reason I ask, looking at their speedway schedule, IF I sign up on say the 29th April, then I can get three GP's in the 30 day period, plus the domestic coverage as well, seems like a bargain!
