i wouldnt touch camskill with a bargepole after the experience i had with them buying tyres.
they do have very competitive prices but for me that was ruined after receiving a set of tyres with one damaged.
They had me over, charging my card (unauthorised payment) for a replacement saying i had damaged it on a tyre machine. it looked like a fork truck had gone through the middle of the tyre wall.
4 for the price of 5 didnt seem like a good deal to me!
Really pi55es me off still thinking about it and its been 2yrs.
