Frequently Asked Questions
What is the Card Show Companion?
The Card Show Companion is a free, mobile-first toolkit designed for collectors and dealers at card shows. It provides quick access to price lookups, flip calculators, centering checks, and a haul tracker — everything you need at a show in one place.
How does the haul tracker work?
The haul tracker lets you log every purchase at a card show: card description, price paid, estimated value, and sport. It calculates your running total spent, estimated total value, and net profit/loss. All data is stored locally on your device.
Can I use this offline at a card show?
The toolkit page loads and works on mobile browsers. The haul tracker uses localStorage so your data persists between visits. For price lookups, you will need an internet connection, but many card shows have WiFi or you can use mobile data.
Is there a cost to use this?
No — the Card Show Companion and all CardVault tools are completely free. No account required, no sign-up, no premium tier.
