That's the price I paid, so that the mats would actually fit the space (none of this Halfords One Size Fits All rubbish).
The driver's side had those little screw in things to keep the mat in place; took a bit of doing but was worth it. Easy to get out but won't move about when in situ.
Don't know how long they will last though; lots of fluff comes off the drivers one, at this rate I'll be down to the backing by summer!
