A vendor case at a card show: rows of PSA graded Pokemon cards standing on green grid shelving, a gem mint Espeon and a gem mint Scizor from Undaunted on the top row, a gem mint Deoxys from Holon Phantoms and a mint first edition Houndoom from Neo Revelation below, and a folded stack of hundreds and fifties resting against the glass beside them.

Why Bartr

The grade is on the label. The price isn't.

Cards move fast and the person across the table has priced them all week. Bartr puts the same numbers in your hand before you shake on it.

  • Know before you agree. Both sides valued, the gap named, and a line telling you whether it is inside the fair band or worth talking about.
  • Test the dealer rate. Move the rate and pick which side it applies to. If an offer only works at 70 percent, you will see it.
  • Keep the receipt. Every trade saved with what you gave, what you got and what it was worth that day. Weeks later you can still check.
  • Nothing to take on trust. Prices come from sold-market data, a card without one shows no price instead of a guess, and a cost nobody entered never becomes a zero.

The same job, at the table.

Pokémon, One Piece, and Riftbound. Raw, graded, and sealed where pricing is available.

A finished bulk scan: eight cards matched and priced at $29,924, one card flagged as missing a price and left out of the total, a 70 percent dealer buy rate, and the first three matches listed with their set, number, grade and price.

A Bartr trade receipt marked value gap: 3,518 dollars given against 5,089 received, a gap of plus 1,571. A PSA 9 Charizard from Stormfront on the given side; a PSA 9 Espeon from Undaunted and a PSA 10 Deoxys from Holon Phantoms on the received side, each itemized with its set and grade, footnoted that values are market references.

For vendors

Your table, on a laptop.

Publish your stock from the app and open it on any bigger screen. Search 102 cards, reprice, mark sales as money changes hands, and watch ask against market and cost per card. Your phone stays the source of truth: the desk queues, the phone confirms.

  • Three views. List for working a queue, tiles for spotting a card, sheet for reading the whole table at once.
  • Margin in the open. Ask, market, cost and margin on every row, and a cost you never entered stays a dash instead of becoming a zero.
  • A shareable list. Customers open a live page of what is for sale. No account, no app.
  • Works on bad convention wifi. A sale made with no signal is parked and sent when the signal comes back.
