Verifying against the live site and live WHOIS/DNS…
Common questions
Is ioffer.com legit or a scam?
AboutUs doesn't label sites "legit" or "a scam": this page lists the dated registration, DNS, HTTPS, mail-authentication and safety checks we could verify, each with its source, so you can decide for yourself.
Who owns ioffer.com?
Nobody has completed AboutUs's owner verification for ioffer.com. That's true of most sites here — it isn't itself a warning sign.

Ioffer.com buy things using reverse auction & negotiation techniques
iOffer is an online marketplace that lets buyers and sellers transact through negotiation and reverse-auction mechanics, rather than fixed prices or traditional competitive bidding. It serves general consumers looking for an alternative to mainstream auction sites. Founded in 2001 and incorporated as IOFFER Inc. in San Francisco, CA, the platform was built around the idea that online shopping should be less stressful and more flexible than conventional web marketplaces.
