“Imagine I’m a seller who has been successfully using Amazon’s Fulfillment by Amazon (FBA) service for some time now. I’m interested in expanding my sales channels to include other online platforms and marketplaces. Can you explain the eligibility requirements for using Amazon Multi-Channel Fulfillment (MCF) as a seller? Are there any specific criteria or qualifications I need to meet before I can start utilizing MCF for order fulfillment on non-Amazon sales channels? Additionally, are there any limitations or restrictions on the types of products or sellers that can use MCF?”
