Where can in car DVD players be purchased from in the UK?
Curry's sells in car DVD players. Amazon UK also has a wide selection of dvd players. Some of these are portable ones that come with the hardware to mount it, but others that do not come with this also come up in a listing of car dvd players, so be careful. If you want the cheapest price, you can try Ebay UK, too, but be wary that the sellers are people, not businesses.
