We buy in small runs, photograph what arrives, and publish the numbers we were given. When a run sells out it stays out until the next one lands.
That is the whole method. It means the shop holds a narrower catalogue than a supermarket and a wider one than a boutique: eight departments, a short list in each, and a stock count worth reading because it is the same number the warehouse has.
Orders leave that one warehouse within two business days, and anything unopened comes back inside thirty.
