If you read Kohl's site, I think it's on the shopping cart page(s), they add tax and estimate shipping during the order process. Once you enter your shipping information your cart will be updated with the appropriate tax and shipping rate. Hope that helps. I had seen this, I think they are both links, when I was BTS shopping online for DD prior to the nearest Kohl's grand opening.
Confirming what I posted - on the Shopping Bag page. Below your order is the following text near the bottom
To estimate shipping, we take the number of addresses you're shipping to and the number of items you're purchasing, and calculate an approximate shipping cost based on our Standard Ground Shipping Costs.
To estimate tax, we take your Shopping Bag Subtotal and apply 6% sales tax, an estimate based on "typical" sales tax percentages nationwide. (Actual sales tax will be calculated based upon your Ship-to Address and the taxability of the items purchased.)
