Sky is giving consumers the chance to get their hands on a £25 M&S voucher when they sign up for unlimited broadband services.
New customers are now entitled to a gift certificate for the popular high street store when they sign up for Sky Broadband Unlimited or Sky Fibre Unlimited.
Sky is also offering introductory discounts on the two packages - with ADSL subscribers entitled to half-price broadband and calls for one year, and fibre customers receiving 50 per cent off for six months.
Households signing up for Sky Broadband Unlimited can take advantage of up to 16Mb download speeds and an unrestricted data allowance.
They also receive inclusive weekend calls to UK landlines and a Sky wireless Hub, which the firm describes as its "best ever".
Customers can also take advantage of free Sky Wi-Fi services in thousands of UK hotspots, allowing them to get online using their mobile devices.
The broadband deal is ordinarily priced at £10 per month for internet and calls, plus a £14.50 per month line rental fee.
However, for the first 12 months the price is reduced to £5 per month plus line rental, allowing customers to save £60 over the course of the year.
Sky Fibre Unlimited offers up to 38Mb download speeds, with all the other deal features - such as free Wi-Fi, inclusive weekend calls and a free wireless router - also applying.
According to Sky, the broadband deal is "lightning-fast", making it ideal for households where there are multiple internet users online at the same time.
This higher-tier unlimited broadband deal is priced at £10 per month plus line rental for the first six months, rising to £20 per month plus line rental.
As such, customers signing up for fibre broadband and calls can also save £60 during the introductory discount period.
Both broadband packages - taken without TV services - include a £25 M&S voucher, providing the new customer signs up online.
The voucher - limited to a maximum of one per household - will be sent out within 45 days of service activation to the email address provided during the registration process.
Consumers have until September 26th to take advantage of this latest broadband offer.
