I've only had one bad experience on Ebay, but that was 2 years ago, before I started buying Tokis, I bought a fake Chloe Paddington, which I thought was real, and when I contacted the seller (who took forever to ship it even though the bag basically had to go over the bridge from Brookyln into Staten Island!), he was very rude about its authenticity, saying that it was all my fault, he was so mean!! Of course this was before I knew about filing claims, so I lost like $120!
But all of my other transactions have been good, I used to buy a lot of Coach bags, and they've all been authentic, and many of the sellers are good with communication. I've also bought concert tickets, and that went well. I still haven't bought a Toki from Ebay, I'm trying to find my inferno with the perfect placement, and all of the ones that I find on there are from our favorite overpriced seller.
