As per description:
A sales tax
is a tax paid to a governing body for the sales of certain goods and services.
The use tax
applies when a resident of the assessing state purchases an item that is not subject to his home state's sales tax. Usually, this is due to out-of-state purchases, as well as ordering items through the mail, by phone, or over the Internet from other states. The use tax is typically assessed at the same rate as the sales tax that would have been owed (if any) had the same goods been purchased in the state of residence.
So since you are going to sell your goods or items "out of state," you should be able to select Sales and Use.
Hope this helps.
