These are marketplace prices — what a card trades at between collectors on eBay, TCGplayer or Cardmarket. A local shop buying for cash pays well under this, and that isn't a bad offer: they carry the rent, the staff and the risk of stock that may sit for a year. Store credit usually beats their cash price.
