Verdict on Oxify

Oxify Quantity Breaks Builder is a solid choice for merchants focused on volume discounts and tiered pricing. The automatic checkout discount application (no promo codes) creates a frictionless experience, and the A/B testing feature is valuable for optimizing bundle offers. Built for Shopify badge confirms quality. The revenue-cap pricing model is transparent, though the lack of a free plan may deter very small stores. A good pick for stores already doing volume and wanting to scale bundle revenue.
