Do you mean bitstamp +10%?
+1
I would say if you want a large amount since its a sellers market, you should be paying a premium.
I don't want to intrude on a trade thread without reason, so I will offer you 30k worth of coins at mt gox +5%.
My question is .. why would I personally pay that when I can just roll on over to Coinbase and get for bit stamp +1%. I think my offer is good. Plenty of people out there that want the cash.
