Product
Every card. Every cost. Every deal.
Cardinal covers the full loop a vendor actually works: find it, value it, offer on it, trade it, sell it and keep the books straight afterwards.
Inventory
Everything you own. Everything you paid.
Add an item once and Cardinal keeps the whole story: what you paid, where it came from, who added it, what it's worth today and how long it's been sitting.
