Shopping cart plugin

hey guys.
I am new to wordpress and I need a shopping cart plugin.
i will make it clear that the user does not pay through the plugin, only orders products and the details will be sent to the admin’s email.

it need to have:
1. adding through the admin panel product / price / description.
2. the user doesnt need to login to buy something.
3. after pressing the “buy” button he will need to fill up few details and it will send the admin an email with all the user’s purchased products.

if i wasnt so clear then post a comment.
thanks so much the helpers!!
