Why don't you try posting on the
eBay sub-discussion forum under shoes, purses and accessories. There are a lot of people there who will be able to give you good ideas. You may just have to wait to see what happens with your paypal dispute since you said you opened one. If they find in your favor, they will likely refund your money if she has enough feedback to be covered. If you paid with a credit card, you can also open a dispute with your credit card company and try a chargeback. I've never done that, but have heard that some people have been successful in this situation.
I also don't think it's probably appropriate to put someone's name on the forum the way you did. Probably fine to list the auction, but putting her actual name - I don't think that's appropriate. If for some reason the bag was found to be authentic, she could take legal action against you for libeling her in print.
In the future, you may want to post auctions you are considering in the "authenticate this" thread so people can help. I hope you are able to get it resolved. Good luck! - I hate it when people take advantage of people by selling fakes and if she did - I hope you are able to get full legal recourse. It is a felony in the U.S. to sell a counterfeit bag - and a second felony to transport through the U.S. Mail Service. I'm not sure what the situation is in Canada, so you may want to follow up with your mail authorities there. You can also contact the criminal authorities in the county where the seller lives and see if they will assist you.
