I was looking for a place to post ads for stuff that I wanted to sell and were too good to just throw away. I came across this website called lookitout.com. It looked quite a reputable and genuine, trustworthy site. It was absolutely free to register and post ads. It seems fairly new and still a work in progress with a moderate level of activity going on. I thought what the heck it's worth a try and you never know your luck. Given that it is free it's definitely worth mention to those looking to sell stuff.

Approximate cost: $0
