Pullnomics
As an eBay Partner Network affiliate, Pullnomics earns from qualifying purchases. Prices compared against TCGplayer market prices via TCGCSV; all figures can change at any time.
Market prices, sealed EV and guides are live. The site does not scan individual eBay listings yet; every card and product page has a button that opens eBay already filtered to listings below market.

Pokémon card market reports

One report per month: which cards and sealed products moved most, what the best and worst booster boxes returned in expected value, and what released. Each report is generated from the site’s own price history, updated nightly while the month is running and frozen when it ends. They record what happened; they are not forecasts.

For the last 7 and 30 days see the price movers page.
