From Card Playbooks
Ideas for running the business side of the hobby.
No hot takes for the sake of hot takes. Just clearer ways to think about inventory, margins, pricing, cash, growth, and the work in between.
Your Inventory Is Not Pure Profit
The cards in your cases still represent capital, risk, and choices you cannot make elsewhere.
Revenue Is a Terrible Scoreboard
A big sales number can hide thin margins, slow turns, and a business that is quietly running out of cash.
The Problem With “Comps”
A recent sale is useful context. It is not a complete pricing strategy.
What a Card Actually Costs You
Acquisition price is only the first line in the real cost of inventory.
When Selling Faster Beats Selling Higher
The best price is sometimes the one that gets your capital back to work.
The Side Hustle Wobble
The awkward stage where the business is too real to guess and too small to waste motion.
