We do not charge sales tax except in the state of Kansas, Wisconsin, Florida, New York, and Illinois because we have a "nexus" (or office) in each of those states to serve you. This rate depends on the county, city and state where you are located.
In states other than KS, WI, FL, NY, and IL, laws apply just like any other online purchase for use tax, sales tax, etc., however we do not collect sales taxes in those areas per the U.S. Constitution's Commerce Clause that regulates interstate commerce transactions.
*These taxes are estimates for the respective states. The tax rate within your county may differ.
