If you’ve ever scrolled through Facebook Marketplace, Instagram, or eBay and seen “OBO” and thought, “what does OBO mean in text?” or “what does OBO mean on eBay?”, here’s your answer upfront: OBO stands for “Or Best Offer.” It is commonly used by sellers to indicate that while a price is listed, they are open to reasonable offers.

In this guide, we’ll cover everything you need to know about OBO: its meaning, practical examples, tips to use it like a pro, common mistakes, and hidden insights that most users don’t realize.

By the end, you’ll navigate chats, sales, and professional communication confidently without second-guessing what OBO means.

What Does OBO Mean in Texting and Online Chat?

In this scenario, OBO communicates flexibility and avoids long, awkward negotiations. It’s particularly useful when you want to test the waters with an offer lower than the listed price without offending the seller.

Why OBO is Important in Texting:

• Saves time for both sender and receiver.
• Signals openness to negotiation.
• Prevents confusion when multiple buyers contact the seller.

Even if you’re not buying anything, knowing this abbreviation ensures you don’t misinterpret texts, emails, or social media messages.

How OBO Works on eBay, Facebook Marketplace, and Online Platforms

When you encounter OBO in online listings, here’s how it usually functions:

1. Seller’s Perspective

• Listing: “Gaming Laptop – $1,000 OBO”
• The seller sets a starting price but is ready to accept offers below that amount.
• It creates urgency while still allowing flexibility in pricing.

2. Buyer’s Perspective

• Listing: “Mountain Bike – $300 OBO”
• Buyers can submit a counteroffer, e.g., $250. The seller may accept, reject, or make a counteroffer.

Pro Tip: OBO listings are not a guarantee of a discount. Sellers often have a minimum acceptable price. Offering a reasonable amount increases your chances of a successful negotiation.

3. Hidden Benefits of Understanding OBO

• Avoid overpaying or underestimating items.
• Identify which listings are negotiable instantly.
• Gain confidence in reaching out to sellers without fear of rejection.

• This usage is common in corporate communication, legal documents, and team emails.

Key Takeaways for Professional Use:

• Always clarify who you represent when using OBO.
