Looking for an alternative?
Here's what changes.
No revenue-based upgrades
Rebolt Pro doesn't charge more as your bundle sales climb; one flat $19.99/mo covers unlimited bundle revenue at any volume.
More offer types included
Combo offers, checkout offers, post-purchase upsells and Smart URLs ship in every Rebolt plan, not as add-ons.
A real bundle builder
Build a Box, mix-and-match, and grid/list/split layouts let you design bundle pages without theme code.
Support that answers
Guided onboarding plus 1:1 Slack support. Fast Bundle merchants tell us this is what they miss most elsewhere.
Rebolt vs Fast Bundle
Yes. Rebolt covers the same core ground product bundles, quantity breaks, BOGO, mix-and-match, and cart upsell, and adds checkout offers, post-purchase upsells, and Smart URLs that Fast Bundle doesn't include. Pro pricing is a flat $19.99/mo with no bundle-revenue cap, so you're not pushed onto a pricier tier as sales grow.
Yes. Buy X Get Y / BOGO deals, volume and quantity-break discounts, and Frequently Bought Together are all included on every Rebolt plan, including the free tier.
No. Rebolt's bundle builder recreates fixed bundles, mix-and-match, and Build a Box offers directly in your Shopify theme, and the onboarding team can help rebuild your existing bundle set during setup.
Rebolt is, once you're past a small store's first sales. Fast Bundle's price rises with your monthly bundle sales: $19/mo up to $1,000, then $49/mo, then $139/mo at $10,000. Rebolt's Pro plan is a flat $19.99/mo with unlimited bundle sales at any volume, so growing stores stop paying more as they get busier.
Yes, Rebolt's Free Forever plan is available with no credit card required, giving every store a no-risk way to try product bundles and upsells before upgrading to Pro.
Switch to the Fast Bundle alternative merchants recommend.
Install Rebolt free, launch your first product bundle in minutes, and upgrade only when you're ready for unlimited bundle sales.
