Don't know about the luck. I chose a seller (2antvysfpf) that had 100% positive feedback, has a YouTube channel
, and has been an Ebay seller since 2014. He goes around or used to go around to different places and countries flee markets and such and has taken videos of the shopping; besides all over Ukraine, there's videos in Germany, Poland, even Russia previously collecting neat unique things.
He did have quite a few things for sale in his Ebay store along with the stamps. But I just checked, and everything of his is gone from the store, listings of the stamps (the only things of his I had saved in the watchlist) are just listed "sold out" now. Maybe luck that I didn't choose his $999 listing for the same stamps, but $100 bill was all I wanted to throw away and give any larger donation to a registered operation (which I have done).
So I don't know what's up at this point. I'll send a message to the seller and see if I get any response. Hopefully the guy didn't get blown up or was just some Russian scam front/hack taking advantage.
