Is anyone making money in the Chrome Web Store?

I haven't been watching the Chrome Web Store for awhile, but now that Unity 3.5 (beta) supports NaCl and Flash, I decided to give it another look. After a quick look around, I don't see a price tag anywhere. I clicked on as many 'Add to Chrome' buttons as I could stand. No prices. I installed some games that I know are sold elsewhere, and played them a little, yet encountered no apparent form of monetization.

Is anybody making (or even charging) money in this venue?
