This behavior causes an infinite loop when attempting to complete a purchase.\n\n## Simulation\n\nThere may be different combinations causing the issue since the weight is used to calculate the proportional shipping costs, making it hard to reproduce.\n\n## Workaround\n\n1.  Configure the free shipping promotion to be applied by the seller.\n2. Configure the \"More for Less\" promotion in the marketplace and restrict it to the seller using the Seller Opt-in feature."}
