Yes, I am bilingual too & find bargains on Ebay France but, I find that I am terribly easy going about quality
I like scarves in different colors, designs & am willing to tolerate a little imperfection, as long as the price is right & I do write to the sellers in French
Basically, I am OK with used (vintage) scarves but others are not & I find Ebay France better for vintage than for near-new
Sure, you will find more vintage scarves in France, daughters or granddaughters selling what they find and these are potentially of lower quality. Hermès is almost a household name in France, everyone knows about it and many have one, collectors only having more. As to near-new, this is effectively more hazardous. Question of luck or knowing the seller (not always the big selling ones).
Here again we have a possible problem with shipping fees : if you obtain a good one at more or less 160 euros, beware of the additional s&h for registered "colissimo".
I have found an alternative, if the seller is ok with this, that is by ordinary registered mail (letter) in a bubble envelope at one third of the tarif and secure since it requires a signature and has a number.
As for ebay restricting shipment outside of France, there is an unwritten law saying that you cannot send out of the country of origin possibly more than one H a month. Or else, it is the seller that has mentioned "livraison en France Metropolitaine" and you cannot get past ebay saying you cannot bid.
This can be bypassed by asking the seller to change his ad, I had this with a charming Corsican who almost pulled her hair out to change the mentions to selling to Europe and leave out livraison to France. We had concluded and no way I could finalize my purchase. Finally she succeeded to change and all went well. It was just a matter of administrative terms in writing.
I must ad that Paypal (speaking for ebay) has decided to ban, in the near future, all selling of H described as "new"
which has not passed by the "maison mère" for authentification and clearance. You can imagine what this would mean for sellers, bringing the item to Paris first...
This is a retaliation of the lawsuit and would stop altogether ebay sales of "new" items, at least for H, I dont know about the others but they have told me it would go in the way of "general rule". Too many disputes they cant handle.
Here's hoping this future is not too near, I'm would certainly not be able to go to Paris and all the authentification process (did it once for a fake) to sell some of my loved scarves.
Best of luck in your findings
