I have just made some changes to our price database to improve the completeness and accuracy of our card prices.
In particular, we should now have better TCGPlayer prices for all the different versions of cards, including most promos, tokens, etc. We are also now showing the TCGPlayer "market price" where available, which should be a more accurate than the previous median prices were.
I have also fixed a few missing prices from our other price sources, such as Card Kingdom, Cardhoarder and Cardmarket.
If you have previously noticed some cards that were not being priced correctly, please have another look at them now and let me know if they have improved.
