Currently quidco have a promotion on Sainsbury home insurance. If you buy combined home insurance (buildings + contents) then they will give you £100 cash back.
I have been quoted £127 for buildings + contents so effectively it means if quidco pays out i would have paid £27 for combined insurance for the whole year.
Please Note that Cash back is not 100% guarantee
