^ I really like those shoes, congrats! That's a great buy criticsdarling!
I remember when I first came into contact with eBay sellers selling fake stuff. I was about to bid on a Coach wallet but then I noticed that the feedback was about 98% and I saw a bunch of negative feedback about fake AF, fake Lacoste shirts and fake Coach wallets! Bottom line: I love eBay and I agree that not everything is fake, but you still have to keep 'caveat emptor' in mind like you should whenever you're thinking about making a purchase.
Regarding the IOD Dior products, it's possible that it could be fake/a replica since people unfortunately like to sell fakes to make a buck. I mean, I never thought that people would fake AF until I saw that seller's negatives!
However, people list discontinued beauty products all the time. In fact, discontinued Bath & Body Works products sell for a pretty penny... but watch out if you're a BBW employee, particularly you don't want to get fired. I've heard that BBW has scouts who scour eBay looking for people who are employees, even going as far as bidding on auctions so they can get your name and verify whether or not you are an employee.
