Seems like a cracking deal for the full 5 seasons.
This is a pre-order price so wont be released until March I think.
Season 1

Summers span decades. Winters can last a lifetime. And the struggle for the Iron Throne has begun. It will stretch from the south, where heat breeds plots, lusts and intrigues; to the vast and savage eastern lands; all the way to the frozen north, where an 800-foot wall of ice protects the kingdom from the dark forces that lie beyond. Kings and queens, knights and renegades, liars, lords and honest men...all will play the 'Game of Thrones.' A new original series based on George R.R. Martin's best-selling 'A Song of Ice and Fire' series.

Season 2

The Battle continues in Westeros with feuding families and power hungry rulers. Five Kings vie for a single, all-powerful throne in the all-new season of Game of Thrones – an epic story of duplicity and treachery, nobility and honour, conquest and triumph.

Season 2 plays out against the backdrop of a fast-approaching winter. In King’s Landing, the coveted Iron Throne is occupied by cruel young Joffrey, counseled by his conniving mother Cersei and uncle Tyrion. But the Lannister hold on the Throne is under assault on many fronts. There’s Robb Stark, son of the slain Lord of Winterfell, Ned Stark; Daenerys Targaryen, who looks to shore up her depleted power through three newborn dragons; Stannis Baratheon, eldest brother of the late King Robert; and Stannis’ brother Renly, who has maintained his own claim since fleeing King’s Landing. In the meantime, a new leader is rising among the wildlings North of the Wall, adding new perils for Jon Snow and the Night’s Watch. With tensions and treaties, animosity and alliances, Season 2 of Game of Thrones promises to be a thrilling journey through a riveting, unforgettable landscape.

Season 3

In Season 3, family and loyalty will be the overarching themes, and many critical plot points from the first two seasons will come to a violent head, with several major characters meeting cruel fates. While a primary focus continues to be on King’s Landing, where the Lannisters barely held onto power after a savage naval onslaught from Stannis Baratheon (brother of the late king), stirrings in the North threaten to alter the overall balance of power in Westeros. Robb Stark, King of the North, will face a major calamity in his efforts to build on his victories over the Lannisters in Season 2, while further north, Mance Rayder (new character, played by Ciarán Hinds) and his huge army of wildlings continue their inexorable march south to scale the Wall. Across the Narrow Sea, Daenerys Targaryen – reunited with her three deadly, fast-maturing dragons – attempts to raise an army of slaves to sail with her from Essos, in hopes of eventually overthrowing the Iron Throne.

Season 4

As Season 4 begins, the Lannisters' hold on the Iron Throne remains intact in the wake of the Red Wedding slaughter that wiped out many of their Stark nemeses. But can they survive their own egos as well as new and ongoing threats?

Meanwhile, an unbowed Stannis Baratheon continues to rebuild his army; the Lannister-loathing ‘Red Viper of Dorne,’ Oberyn Martell, arrives at King's Landing for Joffrey's wedding to Margaery Tyrell; Daenerys Targaryen and her dragons and unsullied force aim to liberate the largest Slavery City in the east...with long-range plans to take back the Iron Throne; and a depleted Night's Watch faces the advance of Mance Rayder's wildling army, who are in turn running from the undead White Walkers.

Season 5

After the shocking deaths of S4, the season begins with a power vacuum that protagonists across Westeros and Essos look to fill. At Castle Black, Jon Snow struggles to balance the demands of the Night’s Watch with those of newly-arrived Stannis Baratheon, who styles himself as the rightful king of Westeros. Meanwhile, Cersei scrabbles to hold on to power in Kings Landing amidst the Tyrells and the rise of a religious group led by the enigmatic High Sparrow, while Jaimie embarks on a secret mission. Across the Narrow Sea, Arya seeks an old friend while a fugitive Tyrion finds a new cause. And as danger mounts in Meereen, Daenerys Targaryen finds that her tenuous hold on the city requires some hard sacrifices.
