BigBoxBigBox vs Fast Bundle
Fast Bundle is one of the biggest bundle apps on Shopify and covers a wide range of offer types. BigBox is deliberately narrower: a build-a-box offer with tier rewards, real cart lines, and flat pricing. Here is how they actually differ.

Sourced from Fast Bundle's own App Store listing and public documentation. Where something is not stated publicly, the cell says so.
| BigBox | Fast Bundle | |
|---|---|---|
| What it is | A focused build-a-box offer on chosen product pages, with up to five reward tiers. | A broad bundling suite: fixed bundles, mix and match, BOGO, volume discounts, frequently bought together, and a bundle builder. |
| Price model | Flat: Starter $14.99/mo (one active bundle), Growth $34.99/mo (unlimited). Price never changes with sales volume. | Tiered by monthly bundle sales per its listing (plans step up as bundle revenue passes set caps); free plan is for development stores only. |
| Bundle model in the cart | Each picked item is its own real Shopify cart line with attribution properties, from the moment it is added. | Per its docs, bundle-as-product adds one combined line item that splits at checkout; shoppers cannot remove individual items in the cart. |
| Tiered rewards | Up to five quantity tiers: percentage or fixed discounts, free gifts, free shipping, applied via Shopify Functions. | Volume discounts and free gift with purchase are listed among its offer types. |
| Targeting and scheduling | Per customer, customer tag, or market, plus scheduling per bundle. | Multi-language and multi-currency support are listed; offer-level targeting details are not stated on the listing. |
| Discount guardrails | Checks connected Shopify discounts, one-click repair, automatic recovery via webhooks, and blocks conflicting bundles on overlapping products. | Not stated on the listing. |
| Analytics | Per-bundle funnel plus paid-order metrics recomputed from real Shopify orders. | Analytics are mentioned on the listing; scope is not detailed. |
| Track record | New app (launched June 2026), no reviews yet. Judge us by the trial. | Launched 2020, thousands of reviews, Built for Shopify badge. A genuinely strong track record. |

An honest read.
Both are real tools. Which one fits depends on what you sell.
- You want many offer types (BOGO, frequently bought together, volume discounts) from a single app.
- You value a long track record and thousands of reviews.
- Your bundle revenue is modest, so sales-capped pricing stays cheap for you.
- You want one focused build-a-box offer done properly, not a toolbox.
- You want flat, predictable pricing that does not rise as your bundles succeed.
- You want each picked item to stay a real, individually managed cart line.
- You want tier rewards, free gifts, and free shipping with health checks and one-click repair on the connected discounts.
Common questions.
Is Fast Bundle a bad app?
Not at all. Fast Bundle is a mature, highly rated app that covers many offer types: fixed bundles, mix and match, BOGO, volume discounts, and frequently bought together. The comparison is about fit and pricing model, not quality.
What does "sales-capped pricing" mean?
Fast Bundle's paid plans are tiered by the monthly revenue your bundles generate (per its listing: plans step up as bundle sales pass set amounts per month). BigBox pricing is flat: $14.99 or $34.99 per month regardless of how much your bundles sell.
How do the two handle the cart differently?
Per Fast Bundle's documentation, its bundle-as-product setup adds the bundle to the cart as a single line item that splits into components at checkout, and shoppers cannot remove individual items from the bundle in the cart. BigBox adds each picked item as its own real Shopify cart line from the start.
Which is better for a simple build-a-box?
If you want one focused offer, a build-your-own box with tier rewards on chosen product pages, that is exactly what BigBox is. If you want a toolbox of many different offer types in one app, Fast Bundle covers more surface.
