eBay has changed things on us again. We used to be able to click the little "print" button on a completed listing and see the best offer price. Unfortunately, that button isn't there anymore.
There are a couple of ways you can still see what a Best Offer Price is.
First, go to Watchcount.com.
Look up the item number.
Then go to the actual eBay listing to see the "sold for" price.
You can also go to a completed listing sold on Best Offer and right click:
Where the selling price is displayed.
Best Offer is a great way to increase sales and be able to negotiate with buyers. Here are some more tips about using Best Offer on eBay.
