Karmakisscom review for Ultimate Upsell & Cross‑Sell

March 24, 2017

This is the best Shopify Upsell App in the market today in my opinion, and I have tested quite a few. Super easy set up, great options for showing upsells, and more importantly - amazing support. I really hope they can continue providing such high level and attentive customer support as this is key for a successful app today.
