One Click Upsell ‑ Zipify OCU

With 9 books currently in my thriller series, pricing that number became a challenge with sales declining with readers reluctant to purchase the entire bundle. On the advice of several other authors, I reduced the number to 6 books (for a more appealing price) but then added an upsell of the remaining titles. Colleagues recommended One Click Upsell -- Zipify OCU to my Shopify page. I've had the APP installed for not quite a week and am already impressed with the results. Granted, not many sales yet...but 66.67% conversion upsell on Ebooks, 50% on audio, and...(gasp!) 100% on print. Hoping this continues...it's a game changer!
