Demo Days Festival review for UpsellPlus Checkout Upsell

5 / 5
March 11, 2026

Their customer service and live chat support is INCREDIBLE! Santiago helped me make a super custom upsell, got creative and found a way to make it happen, and was extremely friendly and efficient. The app itself is amazing, but the people behind it are even better.
