The Kits & Bundles module supports dynamic kit/bundle price, cost, and MSRP calculation. The corresponding Kit Price Auto Calculate, Kit Cost Auto Calculate, and Kit MSRP Auto Calculate toggles are located in Settings → Products & Inventory under the Kit Price & Cost section. When enabled and when the price, cost, or msrp of a kit or bundle is set to 0, SureDone will attempt to auto-calculate those values by combining the values of all of its components respectively. The corresponding bulk headers are iskit_calculated_price, iskit_calculated_cost, and iskit_calculated_msrp.
This feature allows the kits or bundles' price, cost, or msrp to be calculated and updated dynamically as long as the values are set to 0 and are not set by the user. Having specific values would be treated like an override (similar to how ebayprice and ebaytitle work with ghosted values unless overridden). When calculating, each field from the component is multiplied by the second value for that component in the kit's kitlinks field, then summed across all components.
Enabling the above setting/s would auto-calculate prices and costs of Kit as you update the price and costs of the components.
