auction - when auctioneer sells to bidders on behalf of the owner
invitation to treat is when the item is displayed in the action room and when auctioneer starts asking for people to make offers
when a member of the public makes a bid that is an offer
the offer is accepted when the auctioneer drops the hammer - until this is done they can reject any bids and bidder can revoke their bid
payne v cave - acceptance when hammer is dropped
Harris v Nickerson - c failed to recover damages for loss suffered in travelling to a place for an auction that was cancelled
british car auctions v wright - auctioneer was convicted of making an offer to sell an unroadworthy car but on appeal it was only an invitation to treat

auctions without reserve - means there is no minimum price that the item must go for
