I bet you dont go into Tesco and moan about the mark up on the milk, bread and cheese because guess what that is more like 100% mark up.
If you knew what you wanted then you should have asked for the price before hand. Also on the internet and certain merchants do sell non genuine parts so what you got a price on may not be a quality part. I know that a merchant around me has gave me a non genuine part.
Also where did they pick the part up from I know they brought it with them but they had to go and get it and I can imagine getting around London can be quite time consuming ( Never driven around London dont want to either)
