Mr Pig said:I understand what you're trying to do and it's a noble idea. My experience is though that these things are always more hassle that they're worth. I used to use a car forum where a guy said he could get a bulk deal on brakedisks and pads from a leading supplier. Loads of people thought it was a great idea and said they'd take him up on it. He went ahead and started taking names and asking for deposits. Guess what? All that enthusiasm evaporated and the whole thing fell flat. Which is what usually happens.
You've had your twopennyworth so why don't you wait until it fails now and then you can say 'I told you so'. Meanwhile maybe you should let MacB have a go without so much negativity.
