• Use existing store products as upsells in the slider
• Info popups with extra details and images for each addon

Verdict on HD

HD Product Addons offers a unique slider-based add-on experience for product pages. The concept is good for gift wrap, warranties, and customization options. However, with 3.0 stars and only 1 review, it has concerning quality signals. The free plan with 10 revenue orders is very limited.

Key Features

• Quantity breaks and tiered pricing with automatic discount application at checkout
• BOGO and Buy X Get Y offers — no promo codes needed
• Fixed-price bundles, mix-and-match sets, and Build Your Own Box functionality
• Gamified bundle builder with customizable step-by-step layouts and A/B testing
• Cart progress bar, free shipping triggers, campaign scheduling, and built-in analytics

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.
