There is a genuine £14.99 per month and £19.99 per month NOW Sports offer that was emailed to selective NOW account holders.
I didn't get one myself, but over on Hotukdeals website, plenty of people have and I believe reading the comments over on the Hotukdeals website both deals need to be redeemed before Monday the 14th of August.
Here's a screen shot photo of the £14.99 per month offer taken from the Hotukdeals website.
40% discount, allowing for small approximations, is the £19.99 offer.
I knew that Maths O Level would come in useful one day 😛
