£75 to fit a scottoiler isn't bad, assuming it includes the purchase of the scotoiler, they're £70 to buy.
The tyre you can get cheaper elsewhere, as an example I pay just under £100 for a rear Diablo, fitted to a loose wheel and balanced, plus £10 if you want them to take the wheel off and refit it.
