FoneBank.com

Great Web site, very easy to use, and a very quick responce and payment.

I had an old HTC I wasn't using anymore and decided to try and sell it.
A quick check through Google showed a number of websites willing to buy the phone.
Top of the list was FoneBank with a value of £25
I'd had the phone for a few years so thought this was very reasonable.

I went to the FoneBank website, followed the simple steps and instructions, and sent the phone to FoneBank.
Within a couple of days, I had an email saying the phone had been received by them and that a cheque was in the post.
I got the cheque the next day.

It pretty much does what it says on the tin to quote a famous advert, and you can't argue with that to quote another.
