Coinbase is currently at $272 and MtGox is at $266.

So those with cash stuck in Gox can buy bitcoins, and sell them on Coinbase to get their money out.

Yeah I noticed this. Is there any exchange with higher prices than Mt.Gox?

I think this is because Coinbase will "lend" you money during the transfer gap.

For example I can go to Coinbase and lock in a price immediately even though it takes several days for the USD to go through the system. Alternatively I can wire money to bitstamp or mtgox, wait a day or two and then accept whatever the price has moved to.

I made a Coinbase purchase a couple days ago and originially was annoyed by the ~2% premium over bitstamp, but in the end I received a better price than if I had wired money to bitstamp and puchased after the delay.

It's interesting to note that when the price was stable Coinbase better reflected bitstamp prices. IMHO I think Coinbase will tend be priced higher than exchanges during rising periods due to the ability to immediately execute prior to funds clearing.

I had some (not a lot) USD in gox that I was waiting to transfer out once the delays got fixed, and now I am actually making money by buying low on gox and selling high on coinbase. I actually wish I had had *more* USD stuck in gox so I could benefit from this arbitrage!! (Which only turns out to be about 1-2% after fees are taken into account)

What!?  Two U.S. based exchanges where you can arbitrage with bitcoin through ACH? 

CampBX starts ACH USD deposits on 11/20.

Buy at CampBX @ $250.00

Sell at Coinbase @ $276.63

I hope this price spread exists for a while.

You cant ACH into campbx until November 20th

That spread will vanish like a cup cake in front of a fat kid.
