Some users want to offer a base price for a bundle to cover the packing cost or a premium. However, the merge operation can only add the prices of the bundle components.
For example, the base price is $5. The customers can add any 5 variants to get a 10% off. The bundle price is $5 + (total variant prices x 90%) or ($5 + total variants prices) x 90%. I can apply a percentage decrease to the merge operation: MergeOperation
I believe the expand operation is not useful since the bundle parent price is used. But I don’t know the bundle parent price. It’s dynamic
