never get a bargain lol!! but once went to a pug breakers and the lad said i needed a relay.
He made out like it was his tester one and was dead rare and I in my desperation handed over £30. An hour later I walked back in and told him it was the wrong one and took my £30 back, he was wounded lol!!
Cheeky bastard, turns out it was only a few quid for the part from the main dealer iirc.
