thank you for rep. But related with your asking, i have never look the script like this one as a really really free script. and by this time i just buy some script like this one.. Its depends on you i thing... But if you dont want to spend money, better you pick some free script and modify by your self. because as i can see theres nothing impossible by open source
Here is a great site that provides free auction software:
http://www.everysoft.com/auction/ http://www.everyscript.de/eAuction.html http://www.siteinteractive.com/awl/ http://phpauction.org
I haven't used it but I tend to like site that provide Open Source Software.

This software is not free. I think it used to be free but now it is only $8 bucks! That's pretty cheap. It may be worth looking at.
That's what I found for yeah.
I hope this helps.
