I don't know anyone, as I tend to look at items on an 'item -by-item' basis rather than by what a seller has available.
If there's anything you really like, you can post up the auction on the 'authenticate this' forum and someone will be happy to help check it out!! Sometimes it's good to also check the dooney, macys and nordstrom websites at the same time so that you can buy it from one of those places first if they are on sale!
