Yes, I could have got cheaper ones in T K Maxx too, they had 3 or 4 sets at least, as do WILKO, all from about £8 to £20 for 4, but the ones I chose just suited me. (The new  car came without any mats.) 

 

By the way, one minor bug. Does anyone else notice the reflection of the chrome surround of the right hand dashboard vent? I keep seeing it in the driver's door mirror.

Might get used to it, or if not I'll try a neat strip of narrow black tape over the chrome trim.

Yup, and you can even find a thread on here about it. I covered mine with black PVC tape and "cured" the problem. Looks a bit tacky, but better than the reflections IMO.

Funny what you notice "after the event". Just realised that there are no black rubbing strips" on the doors or bumpers - just vulnerable painted metal! Much care needed.
