CDKeys offers Steam downloads of The Elder Scrolls V: Skyrim Legendary Edition for Windows for $5.99. That's tied with our November mention as the best deal we've seen for this version. (It's a low today by $28.) It includes the Dawnguard, Hearthfire, and Dragonborn add-ons. Note: New customers can provide an email address on the CDKeys Facebook page to get a unique coupon code that cuts an extra 5% off.
