Ah, I forgot about that, I was in Costco on Monday and bought it there as it was on special offer but that was £32.60 I think!
I naively thought that local "Unipart" might still be operating under its new ownership, but "for sale" sign up, so Costco was my next stop to get a puncture fixed and to buy oil for Polo.
So to summarise, punctured winter Michelin written off/scrapped and I paid too much for oil - oh joy!
