Overview

Amazon's Add-On program is a system that identifies low-priced FBA items that would be too expensive to ship individually. These products are grouped with larger orders to make fulfillment economically viable. Understanding how this program works is essential for FBA sellers whose catalogs include smaller, lower-cost products, as it directly impacts how and when those items can be purchased by customers.

Key Points / What Sellers Need to Know

• Automatic enrollment — The Add-On program is fully automated. Amazon's system reviews items daily and adds or removes products based on internal cost analysis, with no manual intervention available.
• FBA-only program — Only Fulfillment by Amazon items are eligible for Add-On designation. Merchant-fulfilled items are not affected.
• Order threshold requirement — Customers can only purchase Add-On items when their total order exceeds a minimum value threshold, and the order must include at least one item shipped by Amazon.
• No seller notification — Amazon does not notify sellers when their products enter or leave the Add-On program, making it difficult to track status changes in real time.
• No opt-out within FBA — Sellers cannot request manual removal of items from the Add-On program. The only way to remove an item from Add-On eligibility is to remove it from FBA entirely.

How the Add-On Program Works

Amazon's automated system evaluates FBA inventory on a daily basis to determine which items are cost-prohibitive to ship as standalone orders. Products that fall below certain internal thresholds are flagged as Add-On items and receive a visible "Add-On" badge throughout the shopping experience on Amazon's website. This badge signals to customers that the item can only be purchased as part of a qualifying order. Because the system runs daily and considers dynamic economic factors such as shipping costs and item dimensions, products can move in and out of the Add-On program frequently without any action from the seller.

Pricing and Eligibility Factors

Add-On eligibility is determined by multiple factors, not just the selling price. Two similarly priced ASINs may receive different Add-On designations because Amazon considers additional variables related to shipping costs and fulfillment economics. Even color or size variations of the same parent listing can be treated differently, with one variation classified as Add-On while another is not. This means sellers cannot simply adjust their price to guarantee removal from the program, as the criteria extend beyond the listed sale price.
