At the tail end of last week, Sky launched the Now TV box, a £9.99 online streaming device that gives you access to the Now TV movie and sports services, BBC iPlayer, Demand 5 and more. Now it is pushing its on demand streaming service by offering a promotion that means you'll only need to pay £2.50 per month for the next six months. The normal price is £15.99.

New customers who buy a Now TV box have been offered a different promotion. For them, the first 30-days are free, then it is £8.99 a month for the following three months and then up to the regular £15.99 a month. However, if they sign up to this promotion, the first six months will cost just £15. That represents a saving over the period of £43.95.

The offer is open to anybody who is yet to sign up to Now TV and is running in conjunction with Total Film magazine. When choosing a subscription package online enter TOTALFILMOFFER into the voucher code box and you will apply the discount.

The promotion runs until 4 August 2013.
