It's a con!
The price originally quoted for my iphone4 was £135. They sent me a revised offer of £53 as it had 'excessive wear and tear'. The phone was in good condition so all I can conclude from this is that they lure you in with what looks like a good offer and then try to beat you down as they then want £8.95 to sen it back! It only cost me £6.35 to send in the first place!!! I refused the offer and am waiting to hear back from them but my advice would be to steer well clear.
