I’m not sure if I’m on the right thread so forgive me in advance.
I’ve been busy buying Topsun ungraded cards and I recently found about 5 Japan sellers on Ebay have refunded me because the prices have shot up since I bought the items and they have made up reasons why they can’t ship etc. There is not much I can do but its annoying that one puts in the work to find hidden gems only to find the sellers are embarrassed that they have priced too low and now are refunding the items.
A lot of Japanese sellers on eBay are just middlemen/flippers buying the item after you purchase it through eBay. I’m willing to bet they could no longer source the card from their local craigslist (or equivalent) seller after you purchased said cards. These sellers are easy to spot, as all their listings have completely different background for the cards and normally they have a couple negative feedback stating the seller cancelled the order after paying.
