Frequently Asked Questions

How do I order with a tax-exempt certificate?

We only automatically charge tax to shipping addresses in Ohio. If you're in Ohio, please email us your tax exempt certificate with purchasing email you'll use. We will keep it on file and mark your purchasing email as tax exempt. Then you can place your order normally without being charged taxes.

If you're outside of Ohio, you can go ahead and order now without being taxed. Then, go ahead and email us your certificate so we can mark your account. If we expand in the future, we may eventually charge taxes in your state.

How do I order using a Purchase Order and Invoice?

We'll need to set up a custom order for you and mark it for payment due later. Please email us to receive a quote that includes shipping and taxes. Then, email us your PO. After shipping, we'll email you the invoice with payment details. Please note that if we do not have an existing relationship with your institution, we may require payment before shipping to reduce our risk of fraudulent orders.

Do you offer classroom discounts?

We offer discounts on most products for orders of more than 10 of any one item. Another price decrease is available at 25 pieces - typically what's needed for a classroom. If you are interested in those quantities, please email us and include your item and quantity details for a quote.
