You can use a variable as the second argument to open; the variable will be stringified and treated as a filename.

As for what you save in cookies, it's always best to store as little as possible to prevent problems with data loss. Basically, you should create a sessionID that is a hash of several factors (you don't want to use just IP alone, for example), and set that as the only item in the cookie. Use a database for tracking the current order session, and make sure to include code that will invalid that sessionID after a long enough time that a user will no longer be shopping on your site (30 minutes is the lowest you'd want to go with this).

It's not what you know, but knowing how to find it if you don't know that's important
