I think that is better that you stop the GB: the 17BTC was already reached (actually there are a little more then 19BTC in the Escrow)
We have to calculate refunds & so on.....

So, is it too late or not for 10 shares?
DO NOT buy a single share from these guys until they learn customer support..
And for that matter I think they are oversold anyways.. YET no sign of the group buy being closed.
