Pricing and rating
Fast Bundle is free to install and free for development stores; live stores choose a paid plan that scales with monthly bundle sales: $19/month (up to $1,000), $49/month (up to $3,000), and $139/month (up to $10,000), each with a 7-day free trial and roughly 20% off annual billing. AI frequently bought together and the AI image generator are included on paid plans.
The app holds a 5.0 rating from over 2,800 reviews, with 98% at five stars. Merchants report AOV gains of up to 25%, and consistently praise the flexibility for complex setups, the easy theme integration, and the responsive 24/7 support.
Pitfalls
The free plan covers development stores only, so live stores need a paid plan, and pricing steps up with your monthly bundle sales. It is also bundle-focused, without dedicated checkout or post-purchase upsell placements, and support is offered in English.
Conclusion
Fast Bundle is one of the most capable and flexible bundle apps on Shopify, pairing an exhaustive set of bundle and offer types with AI recommendations, A/B testing, and strong support. If bundles and volume offers are central to your AOV strategy and you want room to build complex setups, it is an excellent choice.
