Yep, sold my site on Flippa, crazy thing is it went for $500! I think I may have been able to get more for it too.
Sadly they charged a lot in fees: $19 listing, $25 escrow and I think it was $12.50 for the final sale fee. On top of that I had to renew the domains which cost around £25.
All in all I think I made $400, which isn’t bad considering it took me 4 hours to setup the site and probably a further 6 hours to write content, plus the research was playing Modern Warfare 2 🙂
