How are shipping costs calculated? We charge a single flat fee for each shipment, plus additional, smaller fees for each item in that shipment. The total shipping charge will be displayed on the last page of the order form, before you submit your order. Here is the equation we use to calculate the total shipping cost:

(Highest Applicable Per-Shipment Cost) + (All Per-Item Costs) = Total Shipping Fee

Note: Per-item costs for some products are a flat rate per unit while for others the per-item cost is based on the product's weight. See rate chart below for details.
