I’ve never bid on an online live auction before.
I've used thesaleroom.com and others. The key point is to realise that when you click the button, that is the bid; there is no "confirm" state/action in the FSM.
If in doubt, have a look at any auction on thesaleroom.com, as a guest.
Assume 30s per lot.
If interested in bidding, you would be wise to create an account on the relevant platform a few days in advance. Then register for the specific auction. If you haven't been "seen" before, there may be a delay of a day or so before you can bid.
I've never left a bid with an auction house, since it is difficult to be sure that doesn't become the
minimum you will be charged.
I see in their T&C
When bidding in the room, or via the telephone the auctioneers charge a buyers premium of 32.5% inc VAT (minimum £2.40 per lot) for bidders that settle their invoice within five days of the sale or 42.5% inc VAT for bidders who pay after this date. All future purchases in future auctions will be invoiced at 42.5% if the bidder pays late in one sale, and a higher deposit may be required for at registration.
When bidding online at eastbourneauction.com or easyliveauction.com the Auctioneers charge a Buyer’s Premium of 30% inc VAT (minimum £2.40 per lot) for bidders that settle their invoice within five days of the sale or 40% inc VAT for bidders who pay after this date. All future purchases in future auctions will be invoiced at 40% if the bidder pays late in one sale, and a higher deposit may be required for at registration.
When bidding via thesaleroom.com the Auctioneers charge a Buyer’s Premium of 38% (minimum £2.40 per lot) for bidders that settle their invoice within five days of the sale or 48% inc VAT for bidders who pay after this date. All future purchases in future auctions will be invoiced at 48% if the bidder pays late in one sale, and a higher deposit may be required for at registration.
All bidders failing to pay by the Wednesday following the sale (i.e. withing 5 days) will be charged an admin fee of £12.00.
VAT where payable on the hammer price of a lot will be refunded on receipt of proof of shipping from the winning bidder that the item has been shipped to a non-EU country. VAT on buyer’s premium will not be refunded. Please note: Cash deposited directly into our bank account will be subject to a surcharge - currently 1.5%, as levied by our bank, Lloyd’s bank.
Note: Where a lot is zero rated for VAT purposes the full buyer’s premium as quoted above is still payable by the bidder.
With shipping on top, buyers need to be very careful how much they are actually spending. I presume this is normal for all live auctions? I would have thought the seller would pay auction fees rather than the buyer.
The actual fees vary, so you have to look at every auction individually. A hammer price of £100 might mutate into £155, i.e. £100*1.30*1.20 (commission, VAT).
Some auction houses do packing and shipping in-house for "small" items. That's likely to be £15-£20. If you send in an external company then I suspect you would be starting at £40.
All that means is that you fix your max price, and work back to your max bidding price.
