Sales Tax Information

Since the South Dakota v. Wayfair decision by the US Supreme Count, we are required to collect sales tax in multiple states.

However, If you are a reseller, school or any other type of business that is tax exempt, you might not be required to pay sales tax. To request tax exemption, please follow these steps.

• Create or log in to your existing account.
• Upload your tax exempt certificate(s) by following this link

If you've already placed your order, please do the following:
• Email or fax a copy (508-393-6688) of your exemption certificate or letter of exemption to us post-purchase
• Please make sure that documentation is signed and dated
• You will receive a retroactive tax refund upon review of your documentation

If you have any questions, please contact us.
