Flightpro review for One Click Upsell ‑ Zipify OCU

One Click Upsell (OCU) is a game-changer for Shopify stores looking to boost Average Order Value (AOV). By showing targeted offers after checkout but before the thank-you page, customers can buy more with a single click—no re-entering payment info. Pros: Instant revenue lift, zero friction for the buyer, and great built-in A/B testing. Cons: The tiered pricing structure makes it a bit pricey for brand-new stores with low sales volume. Bottom line: If you have steady traffic, this app easily pays for itself. Highly recommended.
