We ship almost everything Priority Mail. It is usually the least expensive option and has the advantage of being fast. We always ship the least expensive way and 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. We will use a Regional Priority Mail box. That box will hold a number of student units or hand specimens. Use the chart below to see what shipping of that box 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.

Unless we can use a small flat rate box, we will use Cubic Priority or Regional Priority Mail as our first choice for anything over 16 ounces, as these often are the least expensive rates. The limit is 15 pounds for Regional Priority. These boxes are slightly smaller than the medium flat rate boxes. 
Since Regional Priority Mail is zip code sensitive, and since the ability to assign the correct rate has not been automated, please click the “Combine Shipping” button in the cart if your specimen ships Regional Priority. You will receive an invoice with the correct shipping. 


Note! We sometimes can ship by Priority Mail for less than the rate for Regional Priority and we will select that method if it is the least expensive. Currently, that rate is $13.54 coast-to-coast. It is zip code sensitive. We will refund any shipping overpayment as soon as the order is packed.    

Larger specimens ship in medium and large flat rate boxes at the rates shown above, but those boxes can usually accommodate other specimens as well.     
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.
