How it works

Sealed bids, explained — without the noise.

Sealabid is a sealed-bid marketplace. Buyers place one private offer (“an envelope”) before a deadline. Sellers review all offers after the deadline and choose who they want to deal with — or choose no sale. You’re not charged to submit an envelope; you only pay if you’re selected and the deal proceeds on-platform.

Discretion matters here: sold outcomes are intended to stay private between buyer and seller where supported.

No bidding wars

You don’t fight a moving number. You place your best offer once.

No sniping

There’s no last-second steal. All envelopes lock at the deadline.

Human decisions

Sellers can choose based on reliability and fit — not just the highest number.

Step-by-step

Step 1

Browse

Browse public listings. You can view items without seeing anyone’s offer.

Step 2

Place one sealed offer

You submit one private “envelope” with your best offer. You can’t see other buyers’ offers, and they can’t see yours.

Tip: bid your true maximum. Sealed bidding rewards honesty, not constant monitoring.

Step 3

Deadline

At the deadline, envelopes lock. No last-second sniping. Everyone’s offer is treated under the same conditions.

Step 4

Seller chooses

After the deadline, the seller opens envelopes and chooses who they want to proceed with. The highest offer does not have to win — reliability and fit can matter.

Step 5

Payment only if accepted

You are not charged to place an envelope. Money is only taken if the seller accepts your offer and the deal proceeds on-platform. If you’re not chosen, you’re not charged.

Why buyers like sealed bids

You can win without the circus

In traditional auctions, you can lose because you weren’t watching the timer. Here, you bid once and you’re done.

It’s fairer on your time (and nerves)

No “outbid” alerts. No adrenaline bidding. No guessing games. Just one real offer.

You don’t reveal your hand publicly

Your offer isn’t entertainment for strangers. It stays between you and the seller.

You can stand out beyond price

Sellers may value fast collection, good communication, local pickup, or proven reliability. Your profile and message can help.

Common questions

Can I lose even if I’m the highest offer?+
Yes. Sealabid is built for subjective decisions. Sellers can choose based on price and buyer profile, or decide there’s no sale.
Can buyers see competing offers?+
No. Offers are sealed. You won’t see other buyers’ amounts.
When do I pay?+
You’re not charged to submit an envelope. Payment is only requested if a seller accepts your offer and the deal proceeds on-platform. If you’re not chosen, you’re not charged.
