NOGC.com is based in Oregon, which does not have a sales tax at the present time. We do not charge sales tax on the product shipped out. If we are doing contract services, trade shows, or sell products in other states we do charge the proper tax of that county or state. To customers residing in states other than Oregon, please be aware that, if applicable, the taxing authorities in your state may charge you a "use" tax on your out-of-state internet and/or catalog purchases. While it is not the responsibility of NOGC.com to charge or collect this "use" tax from you at this time, we are alerting our customers regarding this possibility as a courtesy. If you require further information on this issue, we suggest you contact the tax authorities in your state directly.
