Verdict on Zapio:

Zapio is a remarkable completely-free upsell app that includes features other apps charge $20-40/month for. The progress bar and milestone rewards system is a standout feature that drives spending increases. It is still very new with only 9 reviews, so reliability over time is unproven, but the feature set is genuine and the zero-cost entry makes it risk-free to try. A strong option for budget-conscious merchants.
