Post-purchase upsells sit at the exact moment a customer has already committed — credit card swiped, conversion done. That means there's zero risk of hurting conversion and pure upside potential for your AOV.

In this episode, we break down why post-purchase might be the highest-leverage Shopify A/B testing opportunity most brands haven't explored yet.
In this episode of IntelliJAMS, Adam and Alex explore the economics of post-purchase upsells — from a CBD brand that grew AOV 20% overnight to the consumption psychology that makes "buy more now" actually better for long-term LTV.
