These are DUZO's practical rules of play for bidding, selling, payment, and ratings — a more detailed walkthrough than the summary in the terms of use.
DUZO uses "max bids" (proxy bidding): you enter the highest amount you're willing to pay, and the system automatically raises your visible bid for you, step by step, up to exactly what's needed to stay in the lead — never your full max bid at once. No other user can see how high your max bid is.
If another bidder already has a higher max bid than yours, you're immediately outbid and get a notification about it. You can go back and set a new, higher max bid for as long as the auction is running.
Bids increase in standardized increments that grow with the price — the higher the price, the bigger the increment.
An auction ends at its stated end time. A bid in the final minutes does not extend it — the bid has to be higher than the leading bid and has to have reached us before the end time. A bid that arrives at or after the end time is refused. The server's clock decides, not the clock on your device.
A bid is binding. If you win the auction you are obliged to complete the purchase — see "If you win and don't pay".
Maximum auction length is 20 days.
A seller can set a reserve price — a minimum price kept hidden from buyers. If the highest bid doesn't reach the reserve price when the auction ends, the item doesn't sell.
A seller can also set a "buy now" price. As long as the auction is active, a buyer can use "buy now" to end the auction immediately at that price instead of bidding.
On a listing that has not yet received a bid, you can send the seller a price proposal instead of bidding. You do it in the listing's message thread.
A price proposal is binding in the same way a bid is: if the seller accepts, you are obliged to complete the purchase at that price. The proposal is checked against the same limits as a bid — including the limits for new accounts — so you cannot propose a price you would not have been allowed to bid.
The seller can accept or decline. If accepted, the auction ends immediately at the agreed price, exactly as with "buy now", and you pay in the usual way. There are no counter-offers: a seller who wants a different price declines, and you can send a new proposal.
You can only have one unanswered proposal at a time per listing. As soon as anyone places a real bid on the listing, proposals close and an unanswered proposal lapses. A proposal also lapses if the item sells another way before the seller has replied.
On an auction that ended without selling, proposals open again, so buyer and seller can still do business.
All new sellers must apply for seller status. Applications are reviewed manually before being approved or rejected. Buyers do not apply — registering and confirming your email address is enough.
An approved seller can create auctions for their items. If an application is rejected, a new application can be submitted later.
Buyers pay through our payment provider. The amount stays with the provider until the item has arrived — that is what stops a seller being paid for something that was never sent.
For shipped items, the buyer confirms receipt once the parcel arrives, and the amount is then released to the seller. If the buyer does not confirm, the amount is released automatically once 14 days have passed from the day the carrier registered the parcel as delivered — for purchases paid on or after 1 November 2026, and provided the shipping was booked through DUZO and no report and no withdrawal is open for the deal. If the fourteenth day falls on a Saturday, Sunday, Swedish public holiday, Midsummer Eve, Christmas Eve or New Year's Eve, the amount is released only once the next weekday has passed, the same way the withdrawal period is counted. The buyer is reminded at least three days before, and again if a report has been closed in the meantime.
For pickup, the buyer confirms once the item has been collected in person, and only then is the amount released. The same applies to a parcel whose shipping was not booked through DUZO, even when the seller has entered a parcel number themselves: nothing then ties the delivery to this particular order, so the amount is only released by the buyer's confirmation. The same goes for purchases paid before 1 November 2026 — they were made on terms under which only the buyer's confirmation released the money.
The seller can optionally mark an order as "shipped" or "ready for pickup" to keep the buyer informed, but that never triggers a payout. Only the buyer's confirmation does, or, for purchases paid on or after 1 November 2026, the 14 days from the carrier's registered delivery of a parcel whose shipping was booked through DUZO.
If you confirmed by mistake, you can undo the confirmation within 15 minutes. The payout is pulled back, the order returns to its previous state, and any commission and add-ons are returned to the seller. After 15 minutes the confirmation cannot be undone — the money is with the seller, and a problem with the item is handled as a report instead (see below).
The undo window is only for mis-clicks. If the item is broken, missing, or does not match the listing, report the deal — that has no 15-minute limit and is reviewed by us with the chat history and tracking as evidence.
If the item does not arrive, is broken, or does not match the listing: do not confirm receipt — report the deal in the message thread for the purchase instead. Describe what is wrong and attach photos if you can. We read the thread and the tracking, hear the seller, and make a decision.
Ideally, report within 7 days of the item arriving, or of the day it should have arrived. It is not a deadline — a later report is still accepted and reviewed. But as long as the money has not been paid out to the seller, a refund can be made straight from it, which is why it pays not to wait.
Buyer protection comes on top of your rights under the law and does not shorten them. If you buy from a business seller, the Swedish Consumer Sales Act (konsumentköplagen) applies: the seller is responsible for faults that existed when you received the item and appear within three years, and you must complain within a reasonable time after noticing the fault — within two months is always in time. If you buy from a private individual, the Sale of Goods Act (köplagen) applies: complain within a reasonable time after you noticed or should have noticed the fault, and no later than two years after you received the item. You make the complaint to the seller, preferably in the message thread so that it is kept.
Shipping prices are calculated automatically from the carrier's price list, based on the parcel's weight and size (volumetric weight), for all of Sweden.
For pickup, the seller can choose to show an exact address directly on the listing, or just an approximate area for more privacy — in that case, the exact location and time are instead agreed directly between buyer and seller via messaging after purchase.
The seller must hand the parcel over within 5 business days of the purchase being paid. We send a reminder before the time runs out. If it does not happen, the buyer is refunded automatically and the seller receives a strike; at three strikes the right to sell is withdrawn and live listings are ended — the account can still buy and bid. A strike is removed if the delay was caused by circumstances outside the seller's control, exactly as a non-payment strike is for a buyer.
Ratings can only be left between two parties who actually completed a deal together, and only once per deal.
If you believe a rating you received is unfair, you can appeal it. An administrator reviews the chat history and transaction details for the deal before a decision is made. If the appeal is upheld, the rating is removed entirely.
A bid is binding. If you win an auction, use "buy now", or have a price proposal accepted, you have 5 days to pay.
If you don't pay within the deadline, a strike is recorded against the account and the deal can pass to the next bidder or be relisted. The seller is told the purchase fell through.
At 3 strikes, bidding, "buy now" and price proposals are blocked. The account otherwise still works: you can sign in, browse, and above all send messages — precisely so a misunderstanding can be sorted out with the person you dealt with, and with us.
If something went wrong — the wrong item, a seller who stopped replying, a payment that didn't go through — get in touch before the deadline passes rather than letting it lapse. A strike caused by something that wasn't your fault is removed when we see it.
Bidding on your own listing is prohibited. Having someone else do it for you is equally prohibited: family, partners, friends, colleagues or others close to the seller may not bid on that seller's listings, nor may accounts the seller controls. The same applies to any arrangement between bidders intended to drive the price up ("shill bidding").
The sanction is suspension of both accounts — the seller's and the bidder's. A buyer who won an auction where the price was driven up artificially is not bound by the purchase and gets their money back. Manipulating bids in an auction may also be fraud under the Swedish Criminal Code and can be reported to the police.
It is also prohibited to bid without intending to complete the purchase, to misdescribe an item, to harass other users in messages, and to try to move payment off the platform. A purchase made off-platform is not covered by buyer protection — which is the whole reason someone suggests it.
Not everything may be sold here. Weapons and weapon parts — including electroshock weapons and pepper spray — alcohol and tobacco, medicines and drugs, counterfeits and pirate copies, stolen goods, products from protected animals and plants, hate and extremist material, counterfeit currency, lotteries and gambling, recalled and dangerous products — and some other things that are legal to own but not to resell this way.
The full list, with what applies in each category, is on the Prohibited items page. Read it before listing anything you are unsure about; it is the list we ourselves go by when a listing is reported.
A listing that breaks the list is removed. Repeated breaches, and anything that looks like commercial trade in counterfeits, lead to suspension.
Recalled products, and products the EU's Safety Gate alert system has identified as dangerous, may not be sold here — not second-hand either. Search for the item in Safety Gate before selling, for example, children's products, toys or chargers.
If you sell as a business, the listing must also show the manufacturer's name and contact details (and the responsible person in the EU if the manufacturer is outside the EU), information identifying the product, and the warnings and safety information that go with it. What is required is set out in section 19 of the terms.
If you have bought something you believe is dangerous, or an authority needs to reach us about a product: write to our product safety contact point, info@duzo.se, with "Product safety" in the subject line.
