To be honest I cant remember, it was over 2 years ago. All I do remember was that at the time I bought the car Thule didn't make a fitting kit so I bought a tesco value kingsize duvet and used that as a boot liner to stop my bike scratching things.
I had a quick google search and all the online retailers are the same price within about £2 of each other so I guess its a case of finding the ones with the cheapest postage.
I'd be tempted to do a halfords 'click and collect' so that you don't have to go to some random couriers on an industrial estate in the middle on no-where when you inevitably miss the delivery.......
