I think the general consensus of opinion is to shop around and haggle. As for brake fluid, I personally think its a con. They can measure the water content in the fluid and then decide from there. My wife's car had the original fluid for 6 years and then we got it changed when the master cylinder started to leak.
Ask them how much they are charging for oil. It may be cheaper to take your own,as long as its the correct spec. some garages charge up to £13/litre,when you can buy it for as little as £4/ltr
