Here is a sneak peek of one of my tracker setups for delta species booster packs. Usually, Pokémon Delta Species booster packs sell for around $2,000 on eBay, but here are listings that were made less than a minute ago, showing listings for $1300. You could have been the first to see it and the first to buy it with TCG Tracker. Check it out. https://tcg-tracker.app/home
