Taken directly from the Cabela's website in regard to sales tax and for what it's worth:

"Sales Tax is charged on mail, internet, and telephone orders for
deliveries in Nebraska, Wisconsin, South Dakota, Illinois and
Minnesota.

In addition, all orders shipped from a Cabela's Retail store to a state
in which there is a Cabela's Retail store present, will be charged the
applicable sales tax of that state."
