As a small retailer located in Pennsylvania, we are not required to charge sales tax on ordered shipped to other states.  If you are not located in PA, you will not be charged sales tax.
If you’re located in PA, our system will automatically calculate sales tax unless you check the “I’m Tax Exempt” box during checkout.  If this is your first order with us, we’ll follow up after receiving your order to obtain the proper paperwork for nonprofit/government exemption from state sales tax.
