I'm new to Goozex and I sent two things out and through delivery confirmation I can see they were delivered 5 days ago and I was wondering what normal time is to get feedback?
It really depends. Sometimes the buyers are pretty prompt to leave feedback and other times it may take a week. You can shoot them a friendly PM asking if they could leave feedback. But don't worry after 14 days the system will automatically leave positive feedback for the buyers.
Yup, I feel your pain. I have a game out that was delivered on Halloween but still haven't gotten feedback on it, and I can't use the Goozex Exchange to get Up until he sends feedback.
