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.

When it arrives: if it's graded, a slab guard protects the case (and the grade with it); if it's raw, use a sleeve inside a magnetic one-touch. Either way, keep it out of sunlight.
