How Lunchbox Packs lifts AOV with a cart upsell funnel

Many ecommerce brands invest heavily in optimizing product pages, landing pages, and checkout experiences. Unfortunately, after a shopper clicks “Add to Cart,” most stores immediately send them to checkout, missing an opportunity to increase the value of an order that's already in progress.

For brands selling complementary products, this can result in:

• Lower average order values
• Missed accessory sales
• Limited product discovery
• Generic checkout journeys
• Fewer opportunities to experiment after purchase intent is established

Lunchbox Packs extends the buying journey with a post-add-to-cart ConvertFlow Funnel.

Instead of sending shoppers directly to checkout, the funnel launches a popup when a Hydration Pack is added to the cart and introduces complementary products that naturally fit the customer's purchase.

Because recommendations appear after the buying decision has already been made, shoppers can easily enhance their order without interrupting the product selection process. Rather than relying on a single experience, the brand continuously experiments with different funnel variations to improve post-click performance.

After a shopper clicks Add to Cart, the buying decision has been made. Instead of pushing for another conversion, they focus on helping customers discover relevant accessories and upgrades that naturally complement their purchase. That simple shift transforms the period between Add to Cart and checkout into an opportunity to boost AOV.

The funnel strategy

Instead of treating “Add to Cart” as the finish line, Lunchbox Packs treats it as another optimization opportunity.

Step 1. Establish buying intent

A shopper selects a Hydration Pack and clicks Add to Cart. At this point, the customer has already committed to buying.

Step 2. Launch a post add-to-cart popup

Instead of redirecting shoppers immediately to checkout, ConvertFlow launches a popup that starts a dedicated funnel experience. This creates another opportunity to engage buyers while purchase intent is strongest.

Step 3. Recommend complementary products

The funnel presents relevant accessories and upgrades that naturally enhance the original purchase. Instead of forcing customers to browse for additional products, the brand brings those recommendations directly into the buying journey.

Step 4. Increase average order value

Customers continue to checkout with a more complete purchase. Instead of requiring more traffic or higher conversion rates, Lunchbox Packs increases revenue by helping existing buyers buy more.

By extending the customer journey beyond the product page, Lunchbox Packs generates larger orders than its standard ecommerce store experience. The post-add-to-cart ConvertFlow Funnel delivers an average order value higher, which clearly demonstrates the impact of optimizing what happens after shoppers decide to buy.

Takeaways for performance-driven brands

Lunchbox Packs proves an important principle of ecommerce optimization: the product page isn't the only place where revenue can be improved. Brands selling complementary products can apply the same approach by:

• Optimizing what happens after the “Add to Cart” click
• Treating post-add-to-cart experiences as dedicated funnels instead of simple popups
• Presenting complementary products when purchase intent is highest
• Continuously experimenting with messaging, offers, and funnel design
• Measuring success by AOV, not just conversion rate

Remember, the best selling opportunities aren't always before the Add to Cart click; sometimes they're after it.

Here at ConvertFlow, we’ve noticed that high-performance brands don't stop optimizing once a customer decides to buy; they continue improving the buying journey all the way to checkout.
