Shipping & Returns

Telephone Orders — Toll Free: (866) 218-0101

We are open from 9:00 to 4:00 p.m. Central Time, Monday through Friday, to assist you with your orders. If you need to call during off hours or if we are assisting other customers when you call, you can leave orders on our answering machine. Please speak slowly and be sure to include your phone number in case we have trouble understanding anything on the recording. Having full names and addresses for shipping and billing, as well as a purchase order from your institution (if applicable) will help us to ship to you quickly and correctly.


Phone Numbers
We need a phone number to contact you in case of problems with your order at the time of shipping or with delivery. We never give away or sell addresses, phone numbers, or email addresses. Your privacy is important to us.


Fax Orders — (402) 553-0507
We have a Fax Order Form available on our Web site. Print the form and fax us a quick order. If you have trouble printing the fax forms you may need to adjust the size of your fonts on your browser. The form is set for medium fonts. – You can also create your own form!


Shipping charges for Regular US Shipping will be calculated based on your choice of shipping methods and the weight of your total order.  Shipping charges for Canada will be calculated at a rate of 20% of the subtotal of the order and will be shipped the best possible way, unless otherwise specified by the customer. Please note, brokerage fees are not calculated into the shipping cost.  The customer is responsible for brokerage fees or any taxes that may be applied after the shipment has left our facility.


To Expedite Orders
We need zip codes, telephone numbers and product codes if one is listed. This makes our order processing much quicker, and your order will reach you sooner.  Most orders are shipped within 1-2 business days, if all items are in stock (for the most accurate information on in-stock items, please call toll free 1-866-218-0101; see also the Back Orders section).  Please allow up to 10 business days to receive your order.
