I came across a problem with the discount codes on my shop meaning I can't give 5% and free delivery. So I have upped the tyre discount to 10% but then it will charge for shipping meaning that 215 45 17 ZTR with delivery should come out at £624.80 which is about the same amount. So if you go here https://www.motmotorsport.co.uk/store/c20/Circuit_Race_&_Trackday.html and then enter CLIO10MOT at the checkout it should do it.
