Sage & Sill review for NA Product+Upsell A/B Testing

A fantastic app and a fantastic developer! I sent Northern Apps a question because I was having some trouble installing, and Chris responded and got me squared away within minutes. This app lets you choose between manual product selection and automatic product recommendations, which is a phenomenal value at the current price when compared to all the other post-purchase upsell apps that work with Shopify Checkout. Setup was a breeze, and I had a post-purchase upsell offer running within 2 minutes of installing the app. Highly recommend!
