Every card shop has a display case. Almost none have a vending machine.
The display case earns when a staff member is there to open it. The Pokemon card vending machine earns when the shop is closed, when you are restocking, when you are at a different location, and when a customer walks past at 11pm. The product selection and pricing are yours. You stock the machine with your inventory at your margins. Every transaction is a full-margin pack sale with zero staff cost and no display case overhead.
The slot configuration is set for your specific card formats: standard Pokemon booster packs, Elite Trainer Boxes by slot, sports card packs, Magic the Gathering packs, One Piece, Lorcana. The machine is configured for what you actually sell, not a generic display. Browse the full range at trading card vending machines.
