The wording of the creed even on the classic all-leather bags has changed several times over the years, and also changes depending on the materials used on the bag. Mistakes in the creed, like saying a bag is made of full-grain leather when most of the bag is fabric, are also good indicators of a counterfeit.
As to the seller you asked about, we
don't recommend buying from her. A LOT of her customers including several tPF members had had serious issues with her bags, including stains and bad odors and even bags re-colored with
shoe polish. She's also been known to sell fakes. You can read all her Negative and Neutral Feedback here at Toolhaus.org - always check there before buying from any seller. She's also been discussed here many times:

Just to be fair, the recent bag a buyer claimed was fake looks genuine to me but she couldn't even be bothered to post the right serial number. And if you read her comments about the buyers who left bad feedback you can also see how she deals with customers who have legitimate complaints. I wouldn't buy a newspaper from her, much less a purse. DON'T let this poor excuse for a seller ruin your first Coach buying experience!
