I'll have a thunk about that and get back to you - I have to say tho that I have never bothered, after all most canon lenses are excellent so you'd be very unlucky to get a duff one and you have the warranty to fall back on if you are that unlucky...
A lot of dealers dont routinely carry the 100-400is so the chances of them just happening to have two in stock is slight - you need to ring before travelling to make sure theyve got it at all in a lot of places.
