  3. Our contract with you

    1. Our role. Our online platform is a place for Sellers to auction and/or sell goods and for you to bid for and/or buy them. We do not have and never intend to have any contractual involvement in your transactions and at no stage auction, buy or sell or purport to auction, buy or sell any of the products displayed on our site. Any disputes between you and a Seller are just that: we will not become involved. You must therefore take the utmost care to screen the parties with whom you deal. We will not screen the parties or goods on your behalf, and this is a feature of the relationship between you and us that you willingly accept. However, we will consider acting where we receive multiple complaints against a particular Seller.

    2. How your bid/purchase will be accepted. You will receive acknowledgement of your bid/purchase by email and/or SMS communication. This is not acceptance for the purposes of contract law as we will not be contracting with you for the sale of goods. A contract is formed between you and the Seller when you place your bid and/or your purchase is confirmed by the Seller when you use our “buy now” function.

    3. If your purchase cannot be accepted. If the Seller is unable to accept your purchase, the Seller will inform you of this and the Seller will arrange for a refund in accordance with their terms and conditions. Sellers may refuse to accept your purchase for any reason, this may include where they reasonably believe that bid sniping has taken place. Bid sniping is when a bidder places a bid just before the auction closes, without providing an opportunity for anyone else to place a counter bid, often facilitated by bid sniping software.

    4. Availability of our online platform. While we will use all reasonable endeavours to make our online platform available, we cannot guarantee that they will operate continuously or without interruptions. This could affect bidding or other aspects of an auction or sale.

    5. Overseas sales. The Seller may be unwilling to accept purchases from you if you are based outside the UK. It is your responsibility before placing a bid, to ensure you have checked the Sellers terms and conditions regarding sales outside the UK.

  4. Registration to use the Services

If you are the highest bidder after an auction has closed and the Seller accepts your bid, you must complete the transaction and purchase the product, except at the sole discretion of the Seller.

    2. Modes for making purchases. We offer two modes in which you can purchase products using our Services. These are through bidding, or our “Buy-now” function;

      1. Bidding. Some products listed by Sellers on our online platform will be available for auction purchase using a timed bidding system. The particulars of the dates and times relating to that listing will be made clear by the Seller. To place a bid, you must enter your bid amount, click “place bid” whereby you will be taken to a window to confirm your bid and accept our terms and the Seller’s terms and conditions. At this point, you have confirmed your bid amount and understanding that you may not retract or amend your bid except in exceptional circumstances, for example where the Seller has materially changed the description. This will be at the sole discretion of the Seller.

      2. Buy Now. Some Sellers may allow you to purchase products at a fixed price without bidding through an auction process. This will be clearly advertised on the Seller’s listing for the product allowing you to click “buy now”. The Seller’s terms and conditions will apply to that purchase in the same way as when you purchase products by making a winning bid.

    3. You acknowledge that you are responsible for reading the full item listing and the Seller’s terms and conditions before making a bid or purchasing the product.

    4. Sellers are entitled to set applicable minimum bid or reserve requirements and are entitled to change these during the auction period which will be made available for you to view in the listing.

    5. Your placing of a bid entitles the Seller to rely on your bid and as a result you warrant and undertake that you have the legal right to make such a bid and to enter into any such transaction.


  6. Price and payment

    1. Where to find the price for the product. The price of the product will be the price indicated by your winning bid or the price indicated using the “pay now” function and confirmed upon acceptance of your purchase by the Seller.

    2. When you must pay and how you must pay. You must make payment to the Seller for the products using PayPal or Stripe or such other merchant bank provider as available on our online platform. You can select your preferred method of payment when you place a bid or when you use our “buy now” option. Payments will be taken automatically by us using your chosen payment option if you are the winning bidder when the auction closes, otherwise you must pay for your purchase using our “pay now” function when you make purchases using the “buy now” option. Unless otherwise stated, you must pay for the products before they are dispatched. Payments shall be received in the currency specified on the online platform and all prices are exclusive of VAT and other applicable taxes, delivery charges and insurance unless otherwise stated by the Seller.

    3. Deposit. There may be circumstances when a deposit is acceptable, and the outstanding balance can be paid at a later date. When this is an option available to you, full details will be provided in the listing.

    4. Consequences of failing to make payment. This will be at the sole discretion of the Seller and will be governed by their terms and conditions.

    5. The Seller may pass on changes in the rate of VAT. If the rate of VAT changes between your Purchase date and the date the Seller supplies the product, the Seller may adjust the rate of VAT that you pay, unless you have already paid for the product in full before the change in the rate of VAT takes effect.

    6. Commission on charity auctions. In some instances, on charity auctions, costs may be incurred by the charity and a charge may be deducted from the sale proceeds. Accordingly, the charity may not receive 100% of the purchase price. We may also take a commission from the price paid by the successful bidder to cover the costs of our Services. This will be calculated as a percentage of the total price paid. For more information relating to such charges, please contact the Seller and/or

    7. The Buyer’s Premium. We may charge a buyer’s premium on some select listings. This is an additional charge that you will be responsible for paying if you are the successful bidder.

    5. What will happen if you do not provide the Seller with the required information. A Seller may need certain information from you so that they can supply the products to you.

If you do not provide the information within a reasonable time of the Seller asking for it, or if you provide incomplete or incorrect information, the Seller may either end the contract (and clause 10.2 will apply) or make an additional charge of a reasonable sum to compensate them for any extra work that is required as a result. In these circumstances, please refer to the Seller’s terms and conditions.
