I've used Germany eBay
to purchase a number of albums from Germany that I couldn't find anywhere else, using Google Translate to figure things out. I always sent an email to the seller before buying or bidding (in English and German -- not everyone speaks English, despite what some say) to ask if they're willing to ship to the U.S. They usually say yes. I've also done the same with eBay
in the UK but of course without the language problem, again always asking if they'd be willing to ship to the U.S. which seems like just basic good manners. Some sellers don't want to deal with international mail forms which is why I ask. And the Netherlands, Belgium, and elsewhere. Yes, it's a small world.
I haven't done this for France, but I don't see why buying from eBay
France would be any different -- if you can find what you're looking for. Yvert albums and pages do seem to get listed both new and used from what I've seen, but you never see them in the U.S. Then there's the excuse to travel to France to buy what you need and ship it back yourself -- or fit it into your luggage. Something to think about . . . someday.
I've had Yvert pages shipped both from dealers and Yvert itself in France and Marini pages shipped from Marini itself in Italy, both without any problem. But that was before Covid and Brexit. What next, a locust plague?
