Was at my local Walmart Yesterday and stumbled upon the clearance section near the electronics section. Found two copies of Divinity Original Sin for $11.50, so I picked up a copy for myself and a friend and has been great so far.
You are Given a Steam Key to redeem in the box. The Boxed Physical Copy does come with 2 additional Characters & Source Hunter DLC Pack. However, when I redeemed it on steam, It redeemed as Divinity: Original Sin Digital Collectors edition and comes with all the DLC / extras pictured Below.
Note from the Devs:
**Soon you’ll get FREE version of Divinity: Original Sin - Enhanced Edition in your Steam library if you purchased Divinity: Original Sin. That means you’ll then have Divinity: Original Sin & Divinity: Original Sin - Enhanced Edition in your steam library, at no extra cost! Expected to be released at the end of October (27th).**
I know this might be Extremely YMMV but its worth a Shot / Share with you Guys.
Lowest Recorded Sale Price on Steam: $23.99 - 40% off + $5.99 - 40% off for Source Hunter DLC
