I'm planning to refocus my mobile app business, and while I had planned on just continuing on cashing the checks from my other apps, lately I've considered the idea of selling them and really concentrating 100% on the main one.

A few questions: 1. What kind of cost do the popular escrow services charge? I assume it's percentage based, only on successful sale?

2. Do places like FEI sell apps, or just websites?

3. If not, any recommendations on places to sell an app or bundle of apps?
