By the way I bought my flooring online (Camaro ... but believe you can get Karndean if Camaro doesn't work for you) It showed up and the fellas I recommended just fitted it. Saved me a load of £'s doing it that way
Another thing - do go by recommendation on fitting. I've seen it done by someone...
Might want to look at these .. did a great job for me. Also I had Camaro, about 70% of price of Karndean and just as good
