When the auction is open, you can place bids in line with the pre-determined bid increment levels using the bid increase (+) and bid decrease (–) buttons provided.
Every time you place a bid you will be asked to confirm your bid before submitting it, and you will be clearly shown on the screen whether your bid was successful.
A full list of all bids placed is displayed in the bid history table.
Maximum (Proxy) Bids
You are not restricted to placing a bid at the minimum bid amount, but can instead increase your bid and place a maximum (proxy) bid in the system. By setting a maximum bid, the system will automatically bid on your behalf to maintain your position as the highest bidder, up to your maximum bid amount. If you are outbid, you will be notified via email so you can opt to increase your bid if you so choose.
If two or more users place identical bids, the bid that was placed first takes precedence, and this includes proxy bids.

Virtually every lot is sold subject to a reserve price (the minimum price that the auctioneer is authorised to sell for). When you submit a maximum bid, the actual bid placed by the system will depend on whether the reserve price has been met, as defined below.
If your maximum bid is below the reserve price
- The system will place an immediate bid at your maximum bid amount.
If your maximum bid is at or above the reserve price
- The system will automatically increase your bid to be at the reserve, and will only bid again on your behalf if you are subsequently outbid by another bidder (up to your maximum bid amount).
- If another bidder has already placed the same maximum bid or higher, they will be the highest bidder and the system will notify you via email so you can place another bid.
NB : Your maximum bid is kept completely confidential – it's presence or amount are not disclosed to the auctioneer, vendor or any other bidder.

- The current bid on a lot is 90,000. The reserve price has been set at 100,000 (not disclosed).
- Tom wants to bid. The minimum bid amount is 91,000 but Tom decides to place a maximum bid of 97,000. This is below the reserve price, so the system places a bid for Tom at his maximum bid amount and he becomes the highest bidder at 97,000.
- Jane logs on to bid. The minimum bid amount is 98,000 but Jane places a maximum bid of 105,000. The system automatically increases Jane's bid to meet the reserve and she is now the highest bidder at 100,000.
- Tom is notified that he has been outbid. If no further bids are placed Jane would win the lot for 100,000.
- Tom places a bid of 101,000, and Jane’s proxy bid instantaneously outbids him at 102,000 as this is the lowest bid required to make her the highest bidder.
- Tom then places a maximum bid of 105,000. The current bid jumps to 105,000 with Jane as the highest bidder as she placed a proxy bid for that amount before Tom did.
- Tom then places a bid at 106,000 and wins the lot as there are no other bids and it is above reserve.

Timing and Bid Extensions
Lots will close sequentially in lot number order, with each lot scheduled to close 3 minutes after it's preceding lot. However, these times are subject to change due to the following reasons:
Withdrawn, Postponed and Sold Prior Lots
If a lot is withdrawn, postponed or sold prior before the bidding has started, the system will automatically bring forward the scheduled end times of all succeeding lots to maintain a 3 minute gap between lots closing.
Bidding Extension Window
If a bid is placed within the final 30 seconds of the auction's scheduled end time, the auction will be extended by an additional 30 seconds – known as the 'bidding extension window'.
If a bid is placed in the 'bidding extension window', the countdown clock will immediately reset to 30 seconds again, and the auction will only finish when an entire 30 second bidding extension window passes without any further bids being placed, i.e. 30 seconds of 'bidding silence'.
Changes to the Scheduled End Dates
When an extension window is in progress, the bidding software may push back the scheduled end times of subsequent lots to ensure that lots close consecutively and with a minimum 2 minute duration between each one. When this happens, an advisory note will be displayed on the affected lot(s).
NB : Do not leave placing your bid to the last few seconds. It gives you no advantage, you risk your bid not being received by the server in time and you could lose the lot to another bidder.
