we are one of a few places with that type policy, there are loads of ski shops in the uk, just not that many specialist fitters.... no idea why the good guys haven't started it in the USA, the margins on ski boots are being squeezed dramatically every year, and being honest its about the only way we can make enough to stay in business.... remember we are a boot only store, so no skis, gloves, hats, jackets etc which is where the margins are. so we have to rely solely on the boot/fitting/footbeds/liners
if you have a heating engineer install you a new boiler you normally pay for the boiler and installation, same with a service on your car, you pay parts and labour, its not really any different to that, and if more good fitters thought about it that way they would move even further ahead of the chains
