Key Features

• Auto-add free gifts to cart when promotion conditions are met
• Buy X Get Y and BOGO deal configuration with flexible rules
• Auto-apply discount codes for seamless customer experience
• Multiple customizable layout templates matching store branding
• Bundle discounts for increased cart value with zero-coding setup

Verdict on XB:

XB is a simple, free, and Built for Shopify-certified app for stores that just want BOGO and free gift promotions without complexity. With only 4 reviews it is very early stage, but the Built for Shopify badge and completely free pricing make it zero-risk to try. Best for merchants who want a lightweight promotion tool rather than a full bundle builder.

Key Features

• Customize design and layout to match your brand aesthetic
• Display bundles on dedicated pages or embed on product/collection pages
• Single and multiple SKU support with automatic inventory tracking
• Mix-and-match, custom bundles, and gift boxes in one platform
• Fixed, flat, and tiered discounts with conditional logic

Verdict on Advanced

Advanced Bundle Builder by Polar Bear Commerce offers solid bundle building with Built for Shopify certification at a competitive $9.99/month. The personal account manager is a nice touch for setup assistance. At 4.6 stars with 17 reviews, it is still growing but the conditional logic and multi-layout support make it a capable option.
