Those 5970s are worth around 60-70 btc each + shipping. Anyone who offers you less is trying to rip you off. Not sure about the coolers.
There is no reason for you to butt in and poison other peoples deals if you have no intention of buying these cards. It's wrong and very uncool. Prices are relative to peoples expectation of value within their current circumstance and there is no reason for you to dictate other peoples value on any given product.
I bought my new 5970 for 52 BTC (@$5.76/1BTC) with free shipping.
