How do you know if you can trust an eBay seller?
eBay has a feedback system which is their way of letting members who do business keep tabs on each other.
Feedback is made up of comments and ratings left by other eBay members you've bought from and sold to. These comments and ratings are valuable indicators of your reputation as a buyer or seller on eBay. They are included, along with an overall Feedback score, in your Feedback Profile.
How it works
You receive:
+1 point for each positive comment and rating left for you.
0 points for each neutral comment and rating left for you.
-1 point for each negative comment and rating left for you.
When to check it
Before you bid on an item, check the seller's Feedback Profile by clicking the Feedback score next to their User ID, or by using the Find Member feature. Sellers may also want to view a bidder’s Feedback Profile to see how reliable they have been in past transactions.
Feedback Tips
Always leave Feedback after a transaction so that other members may benefit from your experience.
Usually, a high Feedback Score and high percentage is a good sign, but you should always check your trading partner's Feedback Profile to read comments and look for negative remarks.
If you have a private Feedback Profile, you will not be able to sell items on eBay.
Try to resolve any issues before leaving negative Feedback.
You cannot remove Feedback you have left, so be sure to leave only fair and factual comments and ratings that relate to a specific transaction you have with your trading partner.
