Yeah, it’s a heck of a deal.
At the time of writing, I just bought mine and the average was $6.18. Paying more than average gets you all 9 games!
Go grab your copies now before time runs out. It’s a great way to support developers, and give to charity (as you can control how much of your purchase goes to each!).
You can even pay with your Google Wallet (but it wouldn’t recognize the $10 prepaid card I had in there… shucks).
