Spain has over 400 Pokémon card shops across 42 provinces. The cities with the most are Madrid (83), Barcelona (63) and Valencia (26). Prism shows them all on a map of Spain drawn like a Pokémon region, and lets you see the ones near you.
Pick your province on the map or let Prism use your approximate location (it is not stored).
Each shop shows its address and, if it uses Prism, its stock and prices.
Do you run a shop? Prism is free for you too
Shops can join for free: track stock, price it from market value, draw their floor plan to know which shelf holds each card, and appear on the map. There is also a kit with a poster and QR cards for the counter.
