Ever scrolled through Facebook Marketplace or Craigslist and spotted three little letters tucked at the end of a price? OBO. You’ve probably seen it a thousand times. Maybe you even used it once when selling that old mountain bike in your garage. But here is the thing: most people treat those three letters like a throwaway suggestion rather than the strategic bargaining chip they actually are.
If you are wondering what is an obo, it stands for "Or Best Offer."
Simple, right? On the surface, yeah. It just means the seller is willing to haggle. But if you dig into the psychology of peer-to-peer sales, it’s a lot more loaded than a simple "I’m flexible." It’s an invitation to a dance. It’s a signal of urgency, a hint at a seller's mindset, and sometimes, a giant neon sign that says "I have no idea what this is actually worth."
The Mechanics of the Best Offer
When a seller slaps an OBO onto their listing, they are essentially setting a "ceiling" price. They’d love to get $500 for that mid-century modern dresser, sure. Who wouldn’t? But by adding those three letters, they are publicly admitting they will take $450, $400, or maybe even $350 if the item has been sitting in their hallway for three weeks and their spouse is starting to complain about the clutter.
It’s an auction in reverse.
In a traditional auction, like eBay, the price starts low and goes up. With an OBO listing, the price starts high and the seller waits to see who will bite. If nobody hits the "Buy It Now" price, the seller looks at the pile of lower offers and picks the one that sucks the least. It’s a safety net for the seller. They get to test the market's temperature without scaring everyone away with a non-negotiable "firm" price.
Why Sellers Love (and Hate) It
Honestly, selling stuff online is a headache. You deal with "is this still available" ghosts and people who want to trade a broken Xbox for your designer handbag. Sellers use OBO because it casts the widest possible net. It invites the serious buyer who is willing to pay full price and the bargain hunter who is looking for a steal.
But there’s a risk.
If you list something for "$100 OBO," you have basically told the world that $100 is a lie. Nobody is going to offer you $100. They’re going to offer you $75 because you’ve already signaled that you’re willing to move. It’s a psychological permission slip to lowball.
Spotting the Nuance: OBO vs. Neg. vs. Firm
You’ve got to know the lingo if you want to win at this game. You’ll see "Price Negotiable," "Firm," or just the price by itself.
- Firm: Don't even try. If you offer $45 on a $50 "firm" listing, half the sellers won't even reply. They know what they have. They aren't in a rush.
- Negotiable: This is the polite cousin of OBO. It feels a bit more formal, often used in higher-end sales like cars or real estate.
- OBO: This is the wild west. It’s common in yard sales, digital marketplaces, and hobbyist forums. It implies a certain level of "get this out of my house."
I’ve seen people get genuinely offended when they offer a lower price on a listing that doesn't have OBO. That is a quick way to get blocked. Respect the "Firm" tag. But when you see that OBO, the gloves are off.
The Strategy of the Buy: How to Offer
So, you found something you want. It’s listed at $200 OBO. Do you just message them and say "$100?"
No. Don't be that person.
Lowballing without context is the fastest way to get ignored. If you want to actually land the item, you need a strategy. First, do your homework. Look at "Sold" listings on eBay or other platforms to see what the item actually goes for. If the market value is $150 and they’re asking $200 OBO, you have a very strong case.
"Hey, I’m interested in the chair. I see these usually go for around $140-150 online. Would you consider $145? I can pick it up today with cash."
That last part is the "closer." Cash and convenience. Sellers often value their time and sanity more than an extra twenty bucks. If you can prove you aren't going to be a hassle, your lower offer suddenly looks a lot more attractive than a full-price offer from someone who can't show up until next Tuesday.
The "Best" in Best Offer
Remember, "Best Offer" doesn't always mean the highest dollar amount.
Suppose a seller is moving across the country on Friday. It’s Wednesday. Buyer A offers $500 but can’t get a truck until Saturday. Buyer B offers $400 and is standing in the driveway right now with a trailer and a fistful of twenties.
Who do you think wins?
In the world of OBO, "Best" is subjective. It’s a combination of price, timing, and ease of transaction.
Common Pitfalls and Why They Happen
A huge mistake people make is thinking OBO means "half price." It doesn't. Usually, the "wiggle room" is somewhere between 10% and 25%. If you go lower than that, you’re venturing into "Choosing Beggars" territory.
Another weird quirk? The "ghost" OBO. This is when a seller lists an item at a ridiculously low price and adds OBO, hoping to start a bidding war. It’s rare on platforms like Facebook, but you see it in collectibles. They might list a rare Pokémon card for $1 OBO just to get eyeballs on it, expecting people to message them with offers in the hundreds. It’s a bit of a shady tactic, honestly, and it usually results in a lot of annoyed buyers.

The Psychology of "The First Offer"
There is a concept in negotiation called anchoring. The first price mentioned sets the "anchor" for the entire discussion. By listing a price with OBO, the seller has set the top anchor. As a buyer, your first offer sets the bottom anchor. The final price usually ends up somewhere in the middle.
If you offer too low, you break the anchor. The seller realizes you aren't playing the same game and they just stop talking. You want your offer to be low enough to feel like a win for you, but high enough to keep the seller at the table.
Where OBO Shows Up Most
You’ll find this acronym everywhere, but it dominates a few specific niches:
- Automotive Sales: Almost every private car sale is OBO. People expect to haggle over tires, scratches, or that weird clicking noise in the dash.
- Collectibles: Coins, cards, and vintage toys. Because the "value" is subjective, OBO allows the market to decide the price in real-time.
- Real Estate: In some markets, you'll see "Offers Over" or "Guide Price," which is essentially a fancy, high-stakes version of OBO.
- Estate Sales: On the final day of an estate sale, everything becomes OBO because the goal shifts from "make money" to "empty the house."
The "OBO" Ethics: Don't Be a Jerk
There is an unwritten code of conduct here. If you make an offer and the seller accepts it, you are generally expected to follow through. Backing out after your "Best Offer" was accepted is bad form. It wastes time.
Also, don't show up to the pick-up and then try to renegotiate the OBO price you already agreed upon online. That is "The Ol' Switcheroo," and it’s the quickest way to get a one-star buyer rating. If the item is exactly as described, pay the price you agreed on. If you get there and find a giant hole in the upholstery that wasn't in the photos, then—and only then—is it okay to reopen the negotiation.
Taking Action: Your OBO Checklist
Whether you're clearing out your attic or hunting for a vintage leather jacket, understanding the leverage of an "Or Best Offer" tag changes the way you shop.
If you are the seller:
- Use OBO if you want a fast sale or aren't 100% sure of the value.
- Set your "Anchor" price about 15-20% higher than what you actually want.
- Be prepared for lowballs. Don't take them personally; just counter-offer or say "No thanks."
If you are the buyer:
- Always check how long the listing has been up. If it's been there for two weeks, they are much more likely to accept a lower OBO.
- Lead with value. Mention cash, immediate pickup, or a "no-fuss" transaction.
- Don't ask "What's the lowest you'll go?" That forces the seller to negotiate against themselves. Make a real offer instead.
The reality is that what is an obo isn't just a definition; it's a signal of a flexible market. It’s the difference between a rigid retail experience and a human-to-human trade. Next time you see those three letters, don't just see a price tag. See an opportunity.
Next Steps for Success
To get the most out of your next transaction, start by browsing a local marketplace and specifically looking for listings that have been active for more than 7 days with the OBO tag. Practice your negotiation by offering a fair price—roughly 15% below the asking—while emphasizing your ability to pick the item up immediately. This "convenience fee" in reverse is often the secret sauce to getting your offer accepted over higher bids. If you are selling, try adding "OBO" to a stagnant listing today and watch how the increased engagement changes the speed of your sale. This small shift in wording often triggers a psychological "deal-seeking" response in buyers that a flat price simply cannot match.
