@TooManyWeedles asks
TCGplayer and Cardmarket show different numbers. Isn't a card worth the same everywhere?
Jeff answers
Different regions have different buyers, supply, currencies, and selling costs. That's why we built the infinitepulls.com app using current market pricing from TCGplayer and Cardmarket: useful reference points, not a promise that every market agrees. I check the currency and exact version, then compare with sales where I expect to sell. Two different numbers can both be useful when you know what each represents.
