Landing Price are all the costs related to purchasing an item which include additional costs beyond the purchase price of an item. 

Landing Price includes the original price of the product, transportation fees, customs, taxes, tariffs, currency conversion, handling and payment fees.

All of these individual costs are part of the value of the received goods. Tracking the overall item cost helps establish proper sales prices and determine the actual margin per item.
