The Broadleaf Shipping Service includes a handful of out-of-the box fulfillment pricing implementations.
FixedFulfillmentPricingProvider - Basic implementation that applies a flat rate for each fulfillment type.
BandedFulfillmentPricingProvider - Allows setting up pricing bands based on weight or value of items.
VirtualFulfillmentPricingProvider - Similar to FixedFulfillmentPricingProvider, but targeting items that are fulfilled virtually, like downloads.
ShipEngineFulfillmentPricingProvider - Integration with ShipEngine for shipping rates and labels.
