I've just discovered, by looking at the new notice on the bitbills.com home page, that they were using mybitcoin for their transactions.
This annoys the hell out of me. I saw the various concerns/issues people were having with mybitcoin - and chose not to use the service.
I don't recall seeing any indication that mybitcoin was an intermediary when purchasing my bitbills.
I really hope the delay in my order is not due to this - as I ordered a couple of weeks ago.
As far as I'm concerned - my purchase was directly with bitbills - and I consider it their responsibility to provide me with a BTC deposit address that they have control over.
Once the blockchain has reported my deposit to the address they supplied - then I've fulfilled my part of the transaction with them.
It seems the flow-on effects from this mybitcoin fiasco may be larger than I first expected.

EDIT: As far as I can tell, this is little more than an inconvenience for BitBills - and once they have their new ordering solution in place it's business as usual. My order came through just fine
