Just for starters, that seller REALLY needs to work on her "people skills"

I still can't find any record of that wallet, I've even gone back and looked for a purse or wristlet with that same whipstitching around the edge to see if they may have been made to match but I'm not having any luck.
And that part about her getting it as a gift means there's no way she can prove it's authentic. Judging from her Feedback, if you had to get involved in a Paypal claim with a seller like this, it probably wouldn't be a very pleasant experience.
Interesting, someone just posted an auction in the ebay Deals thread for a Limited Edition Legacy Slim Flap that has similar whipstitching.
