Hi all
Just revived this question as I'm dabbling with this idea my self
I've found a multitude of GPL auctions and reverse auctions out there
phpauction which is GPL but also has edited editions etc.
pro bid etc.
there are really very many of them, I also purchase one on ebay, search ebay for auction script, or php auction script.
And also search google for auction script, or php auction script there are really so many it's hard to choose, but also you should be able to navagate to some free GPL ones to try which I'm working on now myself
I'm using a edited version of php auction but it's someones edited editions I think it's called Flux or something.
Ezauction is another one that appearantly can auto install when using a program called Fransico but I think you need to use their hosting and their cpanel for this auto install feature
The auctions range in price from the ones on ebay at: .99 cents, up to around $39.00 and on google searches I've seen free on up to $1500 and anyplace in between.
A good average appears to be around 30 up to 100 bucks and they will usually install it for you as well for that price.
I'm currently having a problem installing mine as a newbie I can't figure out the path's to the sme server, I've got the file permissions figured, but still don't have the auction up and running yet,
I'll post my findings once I get a working install
Hope this helps
