My best pickup this year so far from Amazon is Deus Ex: Human Revolution and the Missing Link DLC. I didn't buy it originally because a couple of my friends told me it wasn't anything special, but when you put it on sale I bit and loved every hour I sunk into it!
For anyone like me who waited until the last minute, I just tried to pick up Civ V but it is now showing as "Currently unavailable". (Civ V GOTY version still shows available though)
Amazon just matched the after coupon price of $36.99 for those with Amazon credit (like me - just ordered on Amazon).

I have a retail ME1, and Amazon DD ME2 and my saves from ME1 imported into ME2 flawlessly. The save import feature just looks for the saved files on your harddrive, so I doubt the distributor makes a difference.
