Both SKUs must have the BuyBox strategy set. Then the FBA product price is optimized for the BuyBox and the FBM product catches up with the FBA product. If the FBA product is sold out, the FBM product is optimized for the BuyBox until the FBA product is in stock again.
Note: FBA & FBM Prime offers must not be combined.
Note: No more than 2 offers in the same condition (FBA & FBM) may be used.
