WTB (want to buy) tangible items
ISO (In Search Of), WTB means you want to buy a real item, not information. On ISO App it works like in search of or looking for (LF): post what you need, your budget, and condition, then neighbors who have it message you.
WTB stands for “want to buy.”You'll see it on collector forums, Facebook groups, and marketplace comment threads. ISO App is built for that demand-first pattern: your wanted post stays visible in the neighbor feed instead of getting buried under supply listings.
Write a clear title (for example “WTB: Graco bassinet” or “ISO: toddler bike 14 inch”), set your budget or mark it open / negotiable, and add hashtags like #kids or #furniture. If you're open to a free handoff, add #buynothing or #free, neighbors who love to give can filter for those tags.
Find what you're looking for, on your terms. A demand-led marketplace for neighbors. Post what you’re looking for first — Marketplace wasn’t built for ISOs. When someone has a match, they reply in-app, you arrange pickup or payment yourselves. ISO App is not a store and does not hold money.
