in DVDs I get 5-8% feedback
I have used feedback services such as feedbackfive in the past and received a much higher percentage, but received a higher number if irritated customers leaving neutral and sometimes even negative remarks, one negative that simply said “you want feedback, here it is”
Amazon sends feedback reminders, which at the time I was unaware of. although most users do not leave feedback, as long as you’re selling quality items and shipping promptly you should receive a good amount of positive remarks. for users who do not leave feedback, its best to leave them be.
