Whatnot auctions vs Sudden Death vs Buy It Now vs offers
Quick answer: On Whatnot, a standard auction adds a few seconds when someone bids late, while a Sudden Death auction (the skull icon) ends exactly when the timer hits zero. Buy It Now is a fixed price with no bidding, and offers let you name your price on Buy It Now items when the seller allows it.

Hi, hello. If you've ever opened a Whatnot show, watched a timer hit zero and had no idea what just happened, this one's for you. Whatnot has a handful of ways to buy, and they look pretty similar on a phone screen at full speed. Here's what each one does, when you're on the hook to pay, and which one to use when you want something without getting carried away.
The Whatnot buying formats at a glance
| Format | How the price is set | Where you see it | Can you back out? |
|---|---|---|---|
| Standard auction | Bidding. Late bids add a few seconds. | Live shows | No. Bids are binding. |
| Sudden Death auction | Bidding. No extra time, ever. | Live shows (skull icon by the timer) | No. Bids are binding. |
| Pre-bid | You set a max before the show. Whatnot bids for you. | Upcoming shows, if the seller turned it on | No. Pre-bids are binding. |
| Buy It Now | Fixed price | In shows and in a seller's shop | Only by requesting a cancellation |
| Flash Sale | Discounted Buy It Now for a short window | Live shows only | Only by requesting a cancellation |
| Make Offer | You propose a price. The seller accepts, declines or counters. | Buy It Now items with offers turned on | Yes, you can cancel an offer before it's accepted (app only) |
Shipping and tax get added on top of all of these, and the shipping cost shows under the item title before you bid or buy. (Bid on an item during a show)
How Whatnot auctions work
Auctions are the main event on Whatnot. The seller sets a starting price and a timer, everyone bids, and when the clock runs out the highest bidder wins. Your saved payment method gets charged automatically. No checkout step, no "are you sure."
Auctions move fast. Whatnot itself says many end in 30 seconds or less. (Bid on an item during a show)
Ways to bid
- Swipe to bid: swipe the Bid button (or click it on the web) to place the next valid bid. You'll see the amount before it goes in.
- Custom bid with Max Bid on: tap Custom, type the most you'd pay, and Whatnot bids for you in increments up to that number. If nobody pushes you, you can win for less than your max.
- Custom bid with Max Bid off: your full custom amount goes in right away as a single bid. Use this when you want to jump the price, not when you want to save money.
Bid increments get bigger as the price goes up, and the next valid bid always shows before you place it.
What is a Sudden Death auction on Whatnot?
A Sudden Death auction is an auction with no overtime. On a standard auction, a bid near the end adds a few seconds so other people can respond. On Sudden Death, nothing gets added. When the timer runs out, whoever was highest before it hit zero wins. You'll know it's Sudden Death because there's a skull icon next to the timer. (How to buy on Whatnot)
What that means for you as a buyer:
- Last-second sniping works on Sudden Death, and it can work against you too.
- Your connection matters. A laggy stream can cost you the item, so a Max Bid is your friend here.
- Decide your number before the timer starts. There's no extra time to think.
How pre-bidding works
If a seller lists items before a show and turns pre-bids on, you can bid ahead of time. A pre-bid works like a Max Bid: you set the most you'll pay, and once the auction runs, Whatnot bids for you in increments, but only when someone bids against you. You don't have to be watching. (Pre-bid on an item before a show)
To pre-bid in the app:
- Open the seller's upcoming show.
- Tap the Store icon in the bottom-right corner.
- Pick the Auction filter to see items that haven't run yet.
- Tap Pre-Bid, enter your Max Bid, and tap Submit.
Two things to know. Pre-bids expire 24 hours after the scheduled show start if the show gets moved or never starts. And on whatnot.com you can only pre-bid from inside the show, not from an item link you found in search. You can track every pre-bid under Activity > Bids.
How Buy It Now and Flash Sales work
Buy It Now (also called Buy Now or BIN) is a fixed price. Tap Buy Now and it's yours, no bidding. Sellers can offer BIN items during a show (look for the Buy Now tab in their shop) and outside of shows on their profile, so you can shop without watching live at all. (How to buy on Whatnot)
A Flash Sale is a Buy It Now item at a discount for a short window during a live show, sometimes only a few seconds. Some sellers run several back to back. You can't make offers on Flash Sale items. (Run a Flash Sale)
How to make an offer on Whatnot
Some Buy It Now items let you make an offer, if the seller turned offers on. You won't be charged unless the seller accepts. (Make an offer on a Buy Now product)
- Open the listing and tap Make Offer (it's just "Offer" on the web).
- Pick a percentage off or type a custom amount.
- Review your payment and shipping, then confirm.
The rules worth knowing:
- If the seller accepts, you're charged the full amount right away.
- If they counter, you have 24 hours to accept or reject in the app.
- If they never answer, your offer expires after 30 days.
- You can cancel a pending offer, but only in the app, under Activity > Offers.
- Referral credit, coupons and Whatnot Gift Cards can't be used on offers. If you have credit to spend, Buy It Now or bid instead.
Can you cancel a bid or a purchase on Whatnot?
Not a bid. Every bid and pre-bid is binding: you bid, you buy. Once you've won or bought something, you can request a cancellation if the seller hasn't made a shipping label yet, or it's been less than 24 hours and the order hasn't shipped. The seller gets two business days to approve or decline, and if they say no or don't answer, the order ships. Frequent cancellation requests can get your account flagged, so don't treat it as an undo button. (Request to cancel an order)
Which format should you use?
| If you... | Do this |
|---|---|
| Want one specific item and can't watch the show | Pre-bid your real max |
| Are watching live and tend to get excited | Custom bid with Max Bid on, set once, hands off |
| See the skull icon | Set a Max Bid before the timer starts |
| Want it now at a known price | Buy It Now |
| Think the BIN price is a little high | Make an offer (if offers are on) |
| Have referral credit to use | Bid or Buy It Now, since credit doesn't work on offers |
Sami's take
From the seller side of the screen: about half of our buyers are repeat buyers. My advice is to decide what you'd pay before the item hits the screen, then let a Max Bid do the work. I only start things at $2 for clearance, never $1, so if you see a $2 start in one of our shows, that's the deal rack.
For vintage clothing, check the measurements the seller gives (ask in chat if they don't) and go by those, not the tag size. Stretchy waists are the safe bet: they fit a much wider range of people, which is also why they sell so well. If you're new to vintage sizing, here's how to figure out your size in vintage clothes.
Whatnot buying FAQ
What does the skull mean on Whatnot?
The skull next to the timer means it's a Sudden Death auction. No extra time is added when someone bids, so the auction ends exactly when the timer runs out.
Are Whatnot bids binding?
Yes. All bids and pre-bids are binding. If you're the highest bidder when the timer ends, you win and your saved payment method is charged automatically.
Does a Max Bid on Whatnot always charge me my maximum?
No. Whatnot only bids up in increments when someone bids against you, so you can win for less than your max if nobody pushes the price.
How long does a seller have to answer an offer on Whatnot?
An offer expires after 30 days if the seller doesn't respond. If the seller sends a counteroffer, you have 24 hours to accept or reject it in the app.
Can I use referral credit or a gift card on a Whatnot offer?
No. Referral credit, coupons and Whatnot Gift Cards can't be used on offers. Referral credit still works on purchases in shows and outside of shows.
