Feedback is important to your reputation because other CPAPAuction members will be able to see if you have negative, positive, or neutral feedback. They can read all of the feedback comments left for you about every single transaction you have made on CPAPAuction.com and view your overall Feedback score.
Many people decide if they want to buy from a CPAPAuction member based on the feedback about that member.
If you have a lot of negative feedback due to bad or poorly handled transactions then this is going to hurt your score and your reputation and other members may be wary or cautious about buying from you.
Always try to resolve any problems with your auction partner first before leaving any negative feedback since feedback is permanent and public.
