Why Facebook groups don't work

Most One Piece TCG trading happens on Facebook. But finding deals there is broken.

Posts vanish in minutes

Hot deals get buried under new posts. Miss one by 10 minutes and it's already gone.

Zero organization

No search, no filters. Scroll past 50 posts to maybe find what you're looking for.

Hours wasted daily

Checking 5+ groups burns time you don't have. And you still miss deals.

One dashboard for the entire market

Every card, every buyer, every seller—organized and searchable.
