About Shipping

We ship almost everything by USPS Ground Advantage Cubic or by Priority Mail Cubic, whichever is the least expensive option. Priority Mail is fast, but Ground Advantage is very close in delivery speed and always cheaper. We normally ship the least expensive way unless you are in a hurry and let us know. We do not add a penny for handling. We refund any overpayment on shipping as soon as the box is packed.   

You can save quite a bit on shipping when you order more than one item.  Use the chart below to see what shipping would cost compared with the small flat rate box a single student unit or hand specimen would ship in. Use your zip code to find the shipping zone.

International buyers: click on the "Combine Shipping" button in the cart or email us using the contact link on the home page for a quote on shipping.

We will use a small flat rate box unless we can ship for less. We will use Priority Mail Cubic or Ground Advantage Cubic with Ground Advantage Cubic as our first choice, since this has usually the least expensive rates. Priority takes a day or two coast to coast. Ground Advantage takes 2-5 days. 
 
The new Cubic rates use three factors: weight, box dimensions and zip code and since the ability to assign the correct rate has not been automated, please click the “Combine Shipping” button in the cart if you are purchasing more than one item. You will receive an invoice with the correct shipping. The chart below will give you a close estimate of shipping cost.

 

For single items, the software will try, but it may overcharge slightly. We will refund any shipping overpayment as soon as the order is packed.  Neurons over chips any day.  

                                                                                                               
Note! If you go straight to checkout with multiple items and don’t request an invoice by clicking on “Combine Shipping,” you may not pay the correct shipping. You will receive an invoice for any underpayment. We’ll refund any overpayment as soon as the box is packed.
