Why merchants are switching from Fast Bundle
These are the four reasons that come up most often from stores moving off Fast Bundle.
Your bill climbs with your bundle sales
Fast Bundle's plans are tied to monthly bundle revenue — $19/mo up to $1,000, $49/mo up to $3,000, then $139/mo at $10,000. Growth means a bigger invoice.
Newer offer types are locked out
Checkout offers, post-purchase upsells, and Smart URLs aren't part of the Fast Bundle toolkit, so stores add separate apps to cover the gap.
Email and chat only
When a bundle setup goes wrong during a sale, merchants say waiting on email support is the most common frustration.
Four tiers to keep track of
Standard 1K, 3K, and 10K plans mean checking your revenue tier before you know your own bill. One flat rate is simpler to plan around.
Why choose Rebolt Bundle instead?
What actually changes once your bundles move over.
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 paid add-ons.
A real bundle builder
Build a Box, mix-and-match, and grid/list/split layouts let you design bundle pages without touching theme code.
Support that answers
Guided onboarding plus 1:1 Slack support — the thing Fast Bundle merchants tell us they miss most elsewhere.
