Rear lens cap on Nikon Coolpix L340 dslr camera?

[Rich-Allen1976]

I've tried to sell an old camera to CEX, they won't take it without a rear lens cap, eh? I know there's a lens cap on the FRONT, and I actually took one this morning, which they said was the wrong one! Eh?! I bought it specially on eBay last year purely so I could resell the camera.

Does anyone know what they're talking about? Cos I've been a camera buff for 20 years and I don't?!

I am aware of Google.
