Consumers have a double incentive to sign up for Sky's Unlimited Broadband & Calls package this week.
Not only is the broadband deal available at half-price for 12 months, but, for a limited period, new customers can choose a £100 reward when they sign up.
Online subscribers have the option of claiming a £100 M&S or Tesco voucher, a £100 Pre-paid MasterCard or a Samsung Galaxy Tab 4 as part of their deal.
This special offer adds to the savings possible with Unlimited Broadband & Calls, which is available at a 50 per cent discount for the first year.
The package ordinarily costs £7.50 per month plus line rental, but during the introductory offer period is priced at £3.75 per month plus line rental.
For this, subscribers gain access to broadband speeds of up to 17Mb and can enjoy unlimited data over the course of the month.
Customers receive a free Sky Hub wireless broadband router - enabling web access via multiple devices throughout the home - along with free Sky Wi-Fi on the go and Sky Broadband Shield.
Weekend calls to UK landlines are also included as part of the broadband package.
Sky is running a separate offer for consumers seeking broadband and TV services as part of the same package.
The firm's Original Bundle & Broadband Unlimited bundle - which comes with a Sky+HD set-top box, Freeview and 35 premium channels - costs £19.98 per month plus line rental.
Subscribers can access a host of on-demand and catch-up features, and upgrade their TV service by adding channel packs such as Sky Movies and Sky Sports.
Original Bundle & Broadband Unlimited is available at a 25 per cent discount for the first year, with customers receiving an additional £75 cashback when they sign up.
