I made an observation today when checking bitcoinstore as to the progress of the 850k run. It had moved back about 6k$ between refreshes, dont know what to make of it, but I tought I should mention it.
I suspect this has to do with the retreat of the exchange rate from a high today of $78 to the low today of $71.90. I suspect that BitcoinStore is keeping all their revenue in bitcoin and displaying that indicator based on the current exchange rate.
