Rigid sided cool box (Sneinton NG2)

I wondered if anyone had a decent size, rigid sided cool box, with a lid that seals well, to gift. I camp in an ordinary van in the Summer and have a problem keeping things like milk, cheese, butter etc cool. I would be very grateful if you have one you don't need anymore. I live close to city centre of Nottingham but am quite happy to travel to collect. Thanks.
