Absolutely love this site, it has saved me hundreds of dollars worth of lost packages because they were found when tracking on this site. There was no disputing the arrival of a package from an eBay sale, the buyer can no longer rip off the seller. It's a great effective tool for the eBay seller, buyer, and even eBay dispute resolutions because everyone can clearly see if the package has been shipped or not. Usually the case is that the buyer DID receive the package even though they are claiming they did not. This saves the seller time and lots of money. Just refer the buyer to this site and their complaint goes away. They know you are smarter than the average person who doesn't know about this site. No more eBay rip-off artists. Yippee!!
