I see your point ziggy, but I know that some shops will look at a bike that they've supplied gone wrong and say "you've messed with this mate, it didn't leave here like that".
What would people think if nothing was available to buy on tinterwebnet, no flights, no clothes, no cars, no bikes or parts etc. We would all be paying full RRP for the same items and be slaves to our LBS' again. Would this be welcomed? I suppose it depends how good/fair your LBS is.
