Born out of killing a broken show spreadsheet.
Card Cache wasn't dreamed up as a generic software template. I built it between university biology classes and weekend setups at NY and NJ card shows because tracking inventory, condition multipliers, and 70–80% cash buy-rates on an Excel sheet falls apart the second three buyers walk up to your table—and convention hall Wi-Fi dies. Every screen in Card Cache exists because I needed it behind my own table first.
