Door Light Lens - Price?

Now that my wife is on maternity we've handed back her works Mk1 Octy and got a nice and cheap 1.4 Mk 1 Leon as car number 2. Recently noticed that the lens cover is missing on the passenger door low level light. The bulb box is still there and works. The missing part is pretty standard (it's on my Scout (hence posting here.....) as well as a host of other VAG cars).

I just spent my lunch hour at the local scrappy without much luck as he either has Octavia Classics (which only have a reflector in the hole where the lense and light should be) or VWs, Audis, etc where I've either been beaten to it or the whole door card is missing!

If we go to a VAG Dealer anyone got an idea how much it will cost? Or equally are any of the sites Sponsors able to help as I'd rather they got the cash than Arnold Shark or equivalent!
