ISO & WTB posts: where they belong (and why feeds blur together)

Marketplace groups mix “for sale,” ISO, WTB, and spam in one scroll. ISO App is only for neighbor wanted posts — so buyers and sellers aren’t talking past each other.

If you’ve posted “ISO” or “WTB” inside a Facebook Marketplace thread or buy/sell group, you’ve probably seen the mismatch: your wanted post sits between for sale listings, shipping offers, and “Is this available?” comments. Neighbors mean well; the format isn’t built for demand-first asks.

ISO App isn’t a replacement for everything Meta does — it’s a dedicated place for neighbor ISO culture: you publish the ask, set budget or Trade, and reply in-app when someone has a match.

Intent matters

For sale → seller-led; buyer hunts.
ISO / LF / WTB → buyer-led; neighbors who already have it respond.
Trade → swap terms upfront on the trade feed.
Buy Nothing (GIVE) → passing items along free on the community free feed.

Practical tips if you cross-post

You can still mention your ISO App link in a group comment — but keep the conversation on ISO when possible so status (open / pending / found) stays visible and moderation tools apply. We’re not affiliated with Meta; always follow each platform’s rules.

For Facebook login, ISO App uses official OAuth so you can sign up with the account you already have — separate from how you post ISOs in the feed.
