Key Features

• Upsell, cross-sell, BOGO, BXGY, and frequently bought together in one app
• Progress bar with milestone rewards encouraging higher cart values
• Automatic free gift insertion and free shipping automation
• Custom rules, scheduling, and market targeting with multi-currency support
• Real-time analytics tracking promotion performance

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.

Key Features

• Donation incentives as alternative to discounts with fixed or percentage amounts
• Curated charities or handpick your own nonprofit partners
• Product-specific and coupon code triggered donation campaigns
• Pre-purchase promotions with social sharing capabilities
• Impact tracking dashboards, reports, and tax receipts

Verdict on Givz

Givz offers a genuinely different approach to boosting sales — donation incentives instead of discounts. This protects margins while building brand loyalty. With 5.0 stars across 15 reviews, merchants love it. However, starting at $19/month with no free plan, it requires commitment. Best for brands with social impact positioning.
