ASP shopping cart

I am looking to get a shopping cart system, used as an include file through the entire website.

requirements:

add to cart one product at a time or multiple products (by check boxes) switchable on the back-end

cookies or session based

calculate shipping based on price or weight

calculate tax (by state or static value)

product attributes (size, color, etc. if the product has any)

check stock level

update stock level

discount

use of coupons

.....

you get the ideea.

all requirements of a shopping cart, easy to implement into any website/s

Guys , some of you are missing my point. I don't need the entire website designed.
All I need is a complete one page, that contains all functions and subs, to allow me to implement it into any website/s as a shopping cart facilities.
