How to show bid history?

Hello.

I have looked all over, but I can’t see where I can enable visitors / members to see the bid history on my auction site. I have the latest version of auction theme and the site is http://www.bidabuck.ca

Members are complaining that they can’t see the history of the bid. (Name and amount)

If the developer never made this feature for the site then how do I add it?

I think this is a very important feature as bidders want to know the bid history.
