Hi
Sorry yes min bid is £10 and min increments of £10
End time terms i copied from another source as below
Last minute bidding sends the auction into 5 Minute Overtime. 5 Minute Overtime Auctions have a normally scheduled end time like any other auction and will end the second the clock strikes the scheduled end time, unless there are bids within the last 5 minutes of the original end time.
Each bid within the last 5 minutes of the scheduled end time starts a 5 minute countdown. If no one bids within those 5 minutes, then the auction ends as soon as the clock reaches the scheduled end time or the extended end time.
