I have an n95 for sale that's around 6 months old now. I haven't really used it as my main phone throughout that time, infact I'm wondering why I bothered keeping it for so long when I hae 5 other phones lol.
It turns out I can get £120 for it by giving it to this recyling company. + they give almost £2 in quidco.
I think it would go for around £160+ postage on ebay, thus I think it's reasonable for me to offer it on here for £145 including postage.
I'm not really looking to haggle, I tend to just offer a set price and if no-one is interested in paying that I'll just whack it on ebay.
