OBO stands for our best offer. You’ll see it tacked onto a price in a classified ad, a Facebook Marketplace listing, or a text about selling something.
It tells you the seller picked a starting number, but they’re willing to hear a lower one.
If you’ve ever scrolled past $50 OBO and wondered whether that meant something else entirely, you’re not alone; it’s one of the most searched shorthand terms in online selling.
This guide breaks down exactly what it means, how people actually use it, and how to respond without looking clueless.
What Does OBO Mean in a Sentence
Picture a garage sale sign that reads Bikes $30 OBO. That price tag isn’t locked in stone. The seller is basically saying, I want thirty bucks, but if you offer twenty-five, I might take it. OBO softens a fixed price into a starting point for a conversation.
This shorthand shows up constantly on Craigslist, Facebook Marketplace, eBay, and even in classified newspaper ads decades before the internet existed. A used car lot, a college kid selling a mattress, a musician letting go of an old amp they all lean on OBO to keep buyers from walking away over a number.
Where OBO Comes From
Before smartphones and marketplace apps, newspaper classifieds ran on tight character limits. Sellers paid by the word, so abbreviations like OBO saved money and space. The habit stuck around because it still solves the same problem: it signals flexibility in three letters instead of a full sentence.
Print classifieds from the 1970s and 80s already used OBO the exact same way people use it on Marketplace today. That kind of staying power is rare for internet slang, and it’s a sign the term earned its place rather than trending briefly and fading out.
OBO Meaning in Text and Chat Apps
Texting didn’t invent OBO, but it definitely kept it alive. When a friend texts selling my Xbox, $150 OBO, they mean exactly what a classified ad means make an offer, and there’s a real chance they’ll say yes to something lower.
Group chats and resale apps like Poshmark or Depop use it the same way. If someone lists a jacket for $40 obo in a Discord server dedicated to reselling, that lowercase version carries identical weight. Capitalization doesn’t change the meaning here.
There’s one less common use worth knowing: in formal or workplace messages, OBO occasionally stands for on behalf of, as in a message sent by an assistant OBO their manager. Context makes the difference obvious a price tag next to OBO means or best offer; a name or title next to it usually means on behalf of.
How to Respond to an OBO Listing
Knowing the meaning is only half the job. Knowing how to reply well is what actually gets you a deal. Sellers who write OBO expect offers, but lowball too hard and you’ll get ignored or blocked.
- Offer somewhere between 10% and 20% below the asking price for a reasonable opener.
- Mention a specific reason for your number, like a scratch you noticed in the photos or a comparable listing you found elsewhere.
- Stay polite and quick to respond sellers often go with whoever seems easiest to deal with, not just the highest bidder.
- Avoid asking what’s your lowest price without offering a number yourself; it puts all the work back on the seller.
- If the item is priced fairly already, a small offer like 5% off still shows respect while leaving room to negotiate.
Common Mistakes People Make With OBO
A lot of buyers and sellers misuse this abbreviation without realizing it, which leads to awkward exchanges or missed sales.
Some people assume OBO means the seller must accept the single highest offer, almost like a silent auction. That’s not accurate. OBO simply means offers are welcome; the seller still chooses whoever they want to sell to, including someone who offers less but pays faster or picks up sooner.
Others confuse OBO with or nearest offer (ONO), a phrase more common in the UK. The two mean nearly the same thing, but ONO tends to suggest the seller expects offers close to the asking price, while OBO leaves more room open.
OBO vs Other Pricing Terms
| Term | What It Means | Where It’s Common |
| OBO | Or best offer price is negotiable, seller picks the offer they like | US classifieds, Marketplace, Craigslist |
| ONO | Or nearest offer similar to OBO, expects offers close to asking price | UK classifieds and resale sites |
| Firm | Price is fixed, no negotiating | Anywhere a seller won’t budge |
| Nego | Short for negotiable, a more formal-sounding alternative to OBO | Classifieds, some resale apps |
| Make Offer | Buyer names a price with no starting number attached | eBay’s built-in offer feature |
Quick Reference Checklist for Using OBO
| Situation | What To Do |
| You’re selling and want flexibility | Add OBO right after your listed price |
| You’re selling but won’t negotiate | Use Firm or Price is firm instead |
| You’re buying and see OBO | Send a specific offer, not just a question |
| You’re texting a friend about a sale | OBO works fine in lowercase, casual tone |
| You see OBO in a work email | Check if it means on behalf of instead of price |
| You want to avoid lowball offers as a seller | List slightly above your true minimum before adding OBO |
Why This Small Abbreviation Still Matters
Three letters shouldn’t carry this much weight, but OBO shapes how millions of everyday transactions happen. It sets expectations before a single message gets sent. A buyer sees it and immediately knows negotiation is welcome. A seller adds it and signals they’d rather sell fast than hold out for a perfect price.
Understanding this term also protects you from a common trap: some sellers now inflate their asking price specifically because they plan to add OBO, expecting buyers to negotiate back down to what the item is actually worth. Knowing this pattern means you’re less likely to overpay just because a number looked negotiable.
