BenchmarkReviews shares a first-hand experience that reveals how little protection eBay and PayPal offer to online sellers, you can read it over here.
Most people are familiar with eBay, the website with an endless catalog ready for purchase. Like many, I've needed to purchase an out of production item and found it available from International sellers. I will also occasionally use eBay to sell random unwanted items to help fund the upgrade or repair. Overall my experience has remained positive, but very recently my opinion of eBay and its banking service PayPal have significantly changed. I have discovered that eBay and PayPal have policies in place that blindly protects buyers, even when they're clearly out to scam and abuse honest sellers.
