How to Build Profitable Amazon Bundles (And How to Prep Them)
Selling single units on Amazon often leads to a race to the bottom on price. Bundling complementary items into a unique ASIN can protect margin and improve conversion, but only if prep and labeling are done correctly.
1) Why bundles increase margins
Bundles can reduce direct listing competition because your offer is unique. They also let you package more value into a single checkout event while keeping your FBA fee structure predictable.
2) Amazon's Bundling Policy
Amazon expects bundle logic to be clear and customer-relevant. Avoid random combinations, and ensure your bundle has a distinct purpose. If required, use a unique UPC or valid GTIN exemption for the bundle listing.
3) The Physical Prep Process
Bundle prep must prevent unit separation in transit and receiving.
- Poly bagging: Keep all bundle items contained together.
- Suffocation warning: Required when bag opening size thresholds are met.
- Boxing: Use corrugate or ready-to-ship packaging for heavier bundles.
4) The "Do Not Separate" Sticker
Every bundle should have a clearly visible "Sold as a Set - Do Not Separate" label on the outer package. Without it, units risk being received as individual components instead of one bundled SKU.

Where does the FNSKU go on a bundle?
The FNSKU should be on the outside of the final bundle packaging, not on internal components.
