I'm building an e commerce website using joomla 2.5 with virtuemart 2.0.22b . Do I need to use another extension for implement bidding function or can I implement bidding function using virtuemart itself ? Pls tell me how to do this.
You know that web shop is not so close to the auction platform.
Auction needs its own component. For a list see http://extensions.joomla.org/extensions/e-commerce/auction
The most used one is http://www.thefactory.ro/shop/joomla-components/auction-factory.html
