Hi everyone – Undrbid.com is an experiment I’ve been working on, and I would greatly appreciate your honest feedback.

An early MVP, Undrbid is where buyers publicly post something they want to purchase, and sellers compete by offering lower prices, higher quality goods/services, or faster delivery/completion before a countdown expires.

Undrbid.com reverses the typical model – instead of buyers negotiating privately, sellers compete openly.

To test it, I ran a manual version of this with a car dealership while pretending multiple dealers were competing.

Result: I got 17.1% off MSRP on a new 2026 Mustang. The dealership’s original offer was only 5% off.

That outcome made me think there might be something here, so I built Undrbid.com to test whether this works at scale.

I’m genuinely curious:

· Would you use something like this?

· What would you try to buy first?

· What would make this more compelling and trustworthy?

And if you've read this far, thank you!
