Although still very high the commission is listed as 26.4% inc VAT all inclusive.
The use of a credit/debit card doesn't seem to attract a fee (legally it can't but some houses do still try to charge one), but the restrictions are a little confusing -
this from there site:
The first part clearly refers to "card holders not present", which is a big restriction, especially for bidders from overseas; the second part, I assume, refers to bidding in person at the auction (or does it mean up to a total of £2000?) and would mean you can't bid on some machines at all unless you have part cash at the very least.PLEASE NOTE: Debit and Credit card payments where the card holder is not present will only be accepted for transactions up to £500. Credit card payments may only be made using chip and pin up to £2,000.
