Conturve US review for UpsellPlus Checkout Upsell

Jan. 16, 2026

Excellent App! Does what we need it to do without being obtrusive. We have seen massive ROI on the investment that we have made. Has a few features that we have not been able to find in other checkout upsell apps (Requires sizing info, customizable thumbnail, true upsell with cart widget etc.) However what sets it apart is the speed of reply from customer support. I bother them a lot with custom requests but I have yet to wait more than 2 minutes to receive a human reply. Amazing!
