Yep, it's just Origin.
You do get a digital version and I'm not too sure about this, but it's possible that if you're buying in the US - you can get a disc version. I heard that a while back and it may not be true or anything, so don't hold me on that.
I must say that personally (I am a fan of discs) I feel that the sale is too good to be true in terms of prices, and you're unlikely to get good prices like this again. Just my opinion though
