Sage & Sill review for Last | Post‑purchase Upsell

Setup was a breeze, integrates with Shopify's edit order API, and lets you use smart auto-upsells with Shopify's product recommendations. The upsell pop-up looks clean and legitimate, not gimmicky or spammy. Did I mention the monthly price is a STEAL compared to the bigger upsell apps? This might end up being my new go-to conversions app. Kudos to Digismoothie, 10/10!
