I just did
Listed my "old" Nokia N95 8GB mobile on ebay - in near new condition as it was broken then repaired, all boxed etc. Listed it for the sort of prices that I'd seen them go for on Gumtree. That'll teach me!
I had 3 messages within the first 2 minutes, and the phone sold with no questions asked in 4mins 25secs!!
Just looked on ebay to see what others were going for and I underpriced it by about £80
Ah well, being an honourable bloke I'm not going to try to wriggle out of it, but boy I'm kicking myself now I should have stuck another £40-£50 on it and would still have got a quick sale!!
