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 the busier they get.
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.
