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.
