Existing Sky customers are being offered the chance to add Sky Sports to their bundle for £10 a month.
The channels will be available at the reduced price for six months and then cost £27.50 extra per month after that.
Sky customers have only a limited time in which to take advantage of the deal, as it launches today (April 1st) and ends on April 4th.
Action currently available on Sky's sports channels includes 116 live games from the Barclays Premier League, live coverage of the Test Series in cricket and every Formula 1 race.
Highlights are also available on demand and via Sky Go.
