Why it matters
ISO (In Search Of) is interchangeable with WTB in most communities. The post signals an active buyer with specific requirements. In Moda's WTB/ISO group, ISO posts tend to be more specific about provenance and condition than generic WTB posts.
The Moda Watch: WTB/ISO Facebook group runs as a dedicated marketplace for ISO posts; sellers respond with what they can source. It's the fastest channel when you know exactly what you want.
