Sky has launched a special offer for new customers signing up for broadband and calls over the internet.
For a limited period, subscribers are entitled to a 50 per cent discount and a free £75 Marks & Spencer shopping voucher.
The gift certificate can be used at M&S stores across the UK.
With new customers entitled to 12 months' at half price, Sky Unlimited Broadband and Calls is available from just £5 per month plus line rental.
For this, subscribers are able to download at speeds of up to 17Mb, and take advantage of an unlimited monthly usage allowance.
They also receive a free Sky Hub wireless broadband router, unlimited Sky Wi-Fi minutes and free weekend calls to UK landlines.
There is no requirement to take Sky TV services with the broadband package.
After 12 months, the price of the broadband deal reverts to £10 per month plus line rental.
The half-price and £75 M&S voucher applies to a number of other Sky broadband deals, including the The Original Bundle & Broadband.
This triple-play package offers a 2GB broadband usage allowance, weekend calls to UK landlines, and more than 40 pay-TV channels.
Subscribers receive a free Sky Hub and also a Sky+HD box, which allows them to pause, rewind and record live television.
Viewers can also take advantage of Sky On Demand - if they connect their set-top box to their broadband router - and Sky Go services.
The broadband bundle is priced at £10.75 per month plus line rental for the first six months, rising to £21.50 per month thereafter.
