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.

Verdict on NML

NML Quick Add to Cart is a completely free app for adding quick-purchase buttons and upsell recommendations to catalog pages. With zero reviews, it is unvalidated. But since it is free, there is no risk in testing. The GA and Facebook Pixel integration is a useful bonus.
