am i missing the point here
i used to work i the garage trade and i know of loads of people who get chummy with thair local motor factors (proper ones) witch are loads cheeper than halfords anyway and just ask for a good price on what you want.
i regulary get 35-50% off halfords prices most of the time.
also have more stock of parts
just tell them what you are doing (building a kitcar) keep going back to the same one and you offten get a bit more off
