hey, a newbie here.can anyone tell me what a shopping cart is?
how does it work ?where can i get one?thanx

You could have a look on HotScripts (http://www.hotscripts.com) , where you will find a huge variety in a number of different scripting languages: PHP,Perl, Java etc.
Some of them are very expensive, while others are open source, GPL etc.,
It depends on your requirements.

i was looking for ready to use ones but thanx.if you want scripts look at www.dhtmlshock.com or www.jave-scripts.com:)

As said already, go to www.hotscripts.com and there will be many ready to use scripts in different scripting languages.

I think you misunderstood my original link to Hotscripts - Did you even look at it??
