Our Verdict
For merchants who want a comprehensive solution with various upsell and cross-sell strategies, including post-purchase options and one-click upsells, Essential Upsell & Cross Sell is the stronger choice.

It is specifically geared towards incentivizing larger orders through bundled offerings and discounts.
Ultimately, the best app depends on the specific needs and product catalog of the merchant. If a merchant values a wide range of features and post-purchase upsells, Essential Upsell & Cross Sell is the better bet. But if the merchant needs a robust bundling and discount engine, Fly: Bundles & Quantity Breaks is the preferred solution.
