It clearly brings a lot of traffic when it runs, and those do clearly turn into some sales (self-reported in our post-checkout survey). We don't yet have enough data to know whether it pays for itself.
If you want some "orders of magnitude" numbers to play with, we're talking about a few bucks per thousand households CPM rates, with a "click through rate" (visitors per watching household) in the few-tenths-of-a-percent range (hard to track but we try). We're still trying to nail down those numbers, but it seems to be a fairly expensive way to find visitors (although within an order of magnitude of other methods, so we're hoping that with tweaking of bids/message/targeting we can make it comparable, because it scales to massive volume really well if you can afford it!).

Did you go for repeat showings to the same people, or did you try to show to as many people as possible once?
A/B Testing, most likely.
Incidentally, this is the first time I've ever seen Google using GWO. It is not good software -- for one thing, this thread exists where if they were doing good A/B testing it wouldn't. I used to joke that they'd swallow broken glass before using it on a site which actually mattered to their business interests. Guess I was wrong. (Although they won't be putting it on any app anytime soon.)
We've been pretty happy with GWO's combination of being a) free, b) easy for marketing+management types to use for reporting, and c) integrated with our Analytics and AdWords accounts.
Just out of curiosity, though: are there competitive hosted solutions you would recommend over GWO? More options would be a good thing to know about...
Let me know if you would like a beta invite.
