I actually had a look at it, and the fact that the SA who deals with Burberry at a high end department store considered it as "not one of our products" - very sloppy stitching and lacking material labels, a lining that Burberry never used, and even the brand label not "quite right" and the person who sold it saying "I don't care if it is a fake, I found it for 2 in a charity shop and sold it, you bought it, not my problem!"
As for options, I think there is also a third option, citizens advise and filing an official claim, yup, it will totally ruin the seller but not her problem, because in all honesty, the seller deserves it. But to ask somebody to wear a fake coat, that is a bit insulting and condoning fakes, sorry if I feel very strongly about fakes, for me it is simply theft of intellectual property and not to mention that a lot of those goods are actually dangerous. As for the time frame, yes, it did slip but she put a winter coat aside to wear it for winter, but as soon as she was made aware, she acted, she thought she struck a total bargain and stayed up to bid.
Look, I am not sure why you think that somebody who worked with a lot of high end goods is not able to identify certain brands they worked with a lot, you didn't work under Anna W and survive, if you didn't know your stuff.
While I am not happy to finance authentication and throw good money after bad, I am totally happy to finance whatever is needed to make it is painful as possible for somebody who sells fakes, because a person like that will go on palming off fake items on others. If somebody sells a fake unknowingly, an then is sorry, a totally different ball game to not caring. I had a few cases where I got fakes and my reaction totally depended on the seller, a "I am sorry, I was given this/found it in a charity shop" not an issue, people think they made a lucky find and weren't aware, it can happen, deliberately trying to take advantage, another ball game. I spent an hour on the phone with a friend in the legal profession earlier today, since she gave the seller the chance to make it right and he didn't he is now obliged to supply her with the item she has bought, which will cost him 2K more. OK with the legal fees, even at mate rates, it will cost more than authentication, but my friend will get a real coat out of it and the seller might not fare very well, I need to cut an onion to shed a tear for him, as for authentication, in case it is a court case, you can involve the brand, who then often will follow up with another law suit, costs them next to nothing.
As for snapping, I guess our definitions of snapping are very different. I simply think fakes are wrong, selling fakes is a crime and should be treated as such with the full force of the law, especially if done deliberately. Fakes are not a victimless crime, personally I would prefer it if all countries would actually do their best. In the case of my friend, I feel a bit guilty that I suggested that she looks on eBay for a winter coat, as her work load and Covid made it quite difficult to go to shops and physically buy items.
I honestly do not understand how somebody can be nonchalant about fakes, put away the economic hit (we all pay for that), the intellectual property theft (no different than picking a pocket), but those people do not stop at pretend designer items, only last week a child died here, parents bought a brand name child car seat 2nd hand, only it wasn't the real thing, the life of a child is a pretty steep price for somebody's personal gain. I know you like eBay, personally I approach it with caution, sadly due to Covid I have almost been forced to buy there again and I am not looking for "super bargains" or "something for nothing", I also don't want to "flip" things and sell them on for more, but the amount of fakes on there being palmed off to people who might not have enough experience, I can report, but they do not seem to do anything about it. I am totally aware that there are scammers on both sides, buyers and sellers.
Btw that
Prada wallet, turned out to be fake and Prada took action, oddly enough the authentication company responded to them and the pictures were of a real item, again, seeing them online, you only see the pictures they put up, what you receive is another matter.
