I hadn't noticed the Costco, Michelin Tyres 20% discount offer this year to date (usually around Easter time). I called them today and the offer starts on the 11th of June. I need two new Michelin Primacy HP 225/55/17 101W tyres for my Vito. Including Vat and fitting. Costco = £187.76 each. Kwikfit = £270.00 each.
