Make-an-offer
A listing without a published price; buyers submit an amount and the seller accepts, counters, or rejects. Standard for owner-priced premium inventory.
When make-offer fits
Make-offer listings work when the seller has a soft floor in mind but wants buyer signal first — usually for one-of-a-kind names where comp data is thin.
Lowballs
Deepnom enforces a min_offer_usd floor per listing so spam and lowballs are rejected at submission time, saving the seller’s inbox for serious buyers.
