Q:
I must charge sales tax in my "home" state of Utah. How do I tell the cart to do that?

In the "Sales Tax" section of the cart configuration form, enter Utah in the first box, and the tax rate in the second box.

Q:
Some of my items are subject to sales tax and some are not. How do I tell the shopping cart what products to leave out of the sales tax calculations?

A:
In the product "item" variable, add the prefix =TF= to your partnumber field. Old number: xyz-1 New number: =TF=xyz-1

Q:
I must charge several different sales tax rates based on what county, etc. people live in my "home" state. How do I allow a variable rate?

A:
If you charge Sales Tax in more than one state, you need to get the shopper to select their state so tax can be calculated.

This demo illustrates how to do that. This type of "forced visit before checkout" page can also be used to make shoppers agree to your policies, etc. Basically whatever you want to make sure that people go there and click what you want them to.
