Package quantities for pricing in the parts list.
Currently when looking at the required parts list for a layout the price of the parts does not take into account the number of that part in a package from the manufacturer. As an example, I require 3 straight sections of track to complete my layout. These sections are sold in packs of 4 at a price of $8.00. If I plug in the $8.00 for the package of 4 (how they are sold) the system will multiply that cost to $24.00 because it thinks each individual track costs $8.00.
