Selling your PS3 games, when, why and how do you choose to sell em?

[jomari]

It dawned upon me, that there are a number of mainstream games i havent played in a while, and was looking at options.

I normally use secondspin.com, but have seen some enticing trade in prices via amazons program.

1. When do you choose to sell your games?

2. Why do you sell your games? aside from the obvious monetary reasons, is it because you dont play em that often anymore? Tired of playing them? Replay value is nil?

3. How or what channels do you sell them through? Ive used secondspin for a while, but for those using amazon, how is it? Craigslist can get a tad complicated at times, and just wanted to know your thoughts.

I was hoping to place this in the gaming discussion section, but mods can move it if needed.
