Yes. Enter code FASTBUNDLEUSER on the pricing page inside the app when you pick a plan, and your first month is free. Our team also migrates your bundles from Fast Bundle for you at no cost. Just start from any migration button on this page.

Yes. AOV.ai Bundles has a free plan with all six offer types and live chat support, and its paid plans are a flat $15.99 to $75.99 a month by Shopify plan, not a revenue share. As your bundle sales grow, that flat price often works out cheaper than Fast Bundle's revenue-tier pricing, which climbs with your revenue.

Yes. The free plan includes all six offer types, live chat support, and up to $500 in additional bundle revenue per billing cycle. Paid plans start at $15.99 a month, remove that cap, and come with a 7-day trial.

No. AOV.ai Bundles is a Built for Shopify app, so it meets Shopify's highest standards for performance. Discounts run on native Shopify Functions, and bundles load through a lightweight, lazy-loaded Preact widget that only loads what each page needs, so it is built to stay gentle on your store speed and Core Web Vitals.

The main difference is pricing. Fast Bundle bills by your bundle revenue, so your cost rises as bundle sales grow. AOV.ai Bundles charges a flat price set by your Shopify plan, from $15.99 a month with no revenue cap. Both cover the core offer types and AI Frequently Bought Together. Fast Bundle adds AI image generation, and AOV.ai Bundles adds a dedicated Bundle Builder and live chat on every plan.

It is guided, not automatic, because bundle data cannot be exported between apps. Install AOV.ai Bundles free, and our team rebuilds each offer with you to match what you run today. You then test at checkout and turn Fast Bundle off. Most stores run only a handful of active bundles, so for many merchants it is quick, not a multi-day project.

You pay a flat monthly price based on your Shopify plan: $15.99 Basic, $25.99 Grow, $45.99 Advanced, and $75.99 Plus, with 20% off on annual billing. There is no revenue cap on paid plans, so no matter how much your bundle sales grow, you stay on the same flat price, unlike Fast Bundle's revenue-tier pricing. Your price only changes if you move to a different Shopify plan.

Fast Bundle prices by your bundle revenue, with plans that step up as your bundle sales cross each threshold, so a strong month can push you into a higher-priced tier and a bigger bill. By contrast, AOV.ai Bundles is priced flat by your Shopify plan with no revenue cap, so its price does not move with your sales.

Popular Fast Bundle alternatives on Shopify include AOV.ai Bundles, Bundler, and Kaching Bundles. Most cover fixed bundles, volume discounts, and mix and match. AOV.ai Bundles stands out for flat pricing by your Shopify plan with no revenue cap, a free plan, a dedicated Bundle Builder, and free guided migration from Fast Bundle.

Both apps offer AI-powered Frequently Bought Together recommendations. Fast Bundle also has AI content and image generation, which AOV.ai Bundles does not, so if AI-generated bundle images are central to how you work, that is one area where Fast Bundle is ahead.
