I've always loved designer accessories, especially handbags. I don't know why but ever since my first coach wristlet in high school, I can't get enough. My mother, who always views my expensive handbag purchases as a waste of money, can't understand it and thinks I'm just trying to show-off. But I really don't feel that way. I just love beautifully made handbags (they're like works of art!) and they are the perfect finishing touch on an otherwise simple outfit (the kind of outfits I like the most). Plus rather than buying a $100-$300 handbag that I wouldn't be able to resell for any kind of return, I buy $1000 handbags that I can resell for almost as much (and well if I buy it used, I usually pay less so that when I resell it, I rarely lose money). So if I'm being smart about it, I actually lose less money on a more expensive handbag and there is always someone willing to buy it from me. And on occasion I sometimes make money.
I'm sure not everyone shares my love of bags, but for those who do, my secret to my handbag "collection" is that it's predominately secondhand and it's always evolving so that the actual number of purses in my possession at any one time is manageable. And I'm always quick to sell a bag (usually on eBay) once I find that I'm not using it as much as my other bags.
Anyway here are the two ways I buy secondhand designer handbags:
1) eBay: my go-to place to sell and my former go-to place to buy. I no longer really buy from eBay anymore because there are just SO MANY fakes in the world these days. When I did buy from eBay, I made sure that A) the seller is legit {usually indicated by a massive amount of positive feedback and also you can sometimes find threads on the PurseForum of legit eBay sellers} , B) I always double-checked with the authenticators on the PurseForum {go to the specific brand you're buying and find the "Authenticate This" thread}. I used to buy Chanels on eBay and would use Etinceler Authentications to ensure those really high ticket items were legit. They cost money, but they know their Chanels and trust me, it's worth the peace of mind. (Another one I've heard of but have never personally used is called Authenticate4u.com). {update: I just used Bababebi.com to authenticate a pre-owned Hermes purchase and found her services to be quick and professional. Since it's not listed on her site, I'll let you know here that it's $65 for an email authentication and $80 for a certificate of authentication. She is the main authenticator on the Hermes thread so if you're ever in doubt about an Hermes purchase and can't get it authenticated on the Purse Forum (I've noticed they're kind of cracking down on authentication abuse), then it's very much worth it to get your expensive Hermes purchases authenticated with her.}
