Basically, if you have a TomTom and take out Zurich car insurance, they give you £50 of Marks & Spencer voucher.
Useful if you know someone with a TomTom. I've found that for my mum and I, Zurich have given the cheapest quotes. For me it's as I have an old car and didn't take courtesy car or breakdown cover.
Anyway, back to the vouchers, you could sell the vouchers for about £40 and call that the cashback. Only thing I haven't figured out yet is how to use this offer at the same time as quidco, hoping that some genius HUKDer can help me on that!
Hope this offer helps people.http://www.zurichinsurance.co.uk/insurance/landing/tomtom1.htm?mkt=ZTOM5
