1. Virtuemart Cart Pro Extension
It's great for any sites to show the cart on the left / right side, coming with ajax functionality.
Have you ever thought about making an innovation for your cart system? An important
element of your site seems to be ignored. The default cart doesn't allow your client
checking cart directly and they get annoyed when being redirected to another page.
Virtuemart Cart pro can make it disappear with the Ajax technology.
