I ordered Bioshock Infinite on 18/9/2013 (5 days ago).
Paid BTC 0.3186 at 17:01. The payment was transferred out at 21:32: https://blockchain.info/address/1F4AZzcNwvzTVV1zYMVdbWPipkU42EtXAR
No game code and no response from emails sent to support@ and orders@...
UPDATE: Received a code this morning (24/9/2013) at 01:23.
I ended up using http://www.crypto4games.com/ and had a good experience there, with immediate responses to my enquiries. I will use this one instead of SteamBits in the future.
