How would I go about creating a shopping cart for a website without using a database?

I am not aiming to actually have my products purchased, as this website is for simulating an online purchase experience.

What I want is for the user to input all their information and view the products they can purchase and in what quantity on one page. I am not too worried about the information being secure, as I will state that because it is a simulation, no real personal information should be given. The information will all be cleared when the user leaves the website.

After clicking "Review Order" or something like that, I want the page (after verifying the user's information) to show the order so far. The button to actually process and send the order will not work.

Maybe this will help:

Order Page
1. Item 1 (Price: ____) Quantity: [ ]
2. Item 2 (Price: ____) Quantity: [ ]

(These are input fields.)

(This button will lead to this next page, with items and their quantities remembered as well as the user/credit card information remembered.)
