Game UK has a great deal on an Elder Scrolls Bundle.
Elder Scrolls Bundle = £20.61 (about $33 USD) (Steam)
Elder Scrolls III Morrowind Game of the Year
Elder Scrolls IV Oblivion Game of the Year
The Elder Scrolls V: Skyrim
The Elder Scrolls V: Skyrim – DawnguardThe Elder Scrolls V: Skyrim – Hearthfire
It’s a UK site but non-UK people have been able to purchase it. The bundle comes with one Steam activation key, which activates all the games. So no splitting unfortunately.
