BigBoxMix-and-match bundles, without duplicate products
Most bundle setups force you to create and maintain separate bundle SKUs. BigBox lets shoppers mix and match real products on the product page instead: they pick the variants they want, rewards unlock as they add more, and checkout uses real Shopify cart lines.

How mix-and-match works with BigBox.
Define the pick list
Select the products or collections shoppers can mix from. Restrict variants where needed and hide anything out of stock so the offer never sells what you cannot ship.
Reward bigger mixes
Set up to five quantity tiers: percentage or fixed discounts, free gifts, or free shipping. The progress bar nudges shoppers toward the next tier.
Keep operations untouched
Selections land in the cart as real Shopify lines with BigBox attribution. Inventory, 3PL feeds, and order reporting keep working without workarounds.
Made for stores where choice sells.
Coffee, snacks, cosmetics, candles, apparel basics: anywhere shoppers want their own combination.
Any combination you allow
Shoppers combine products and variants freely within the rules you set: minimum and maximum items, allowed variants, in-stock only.
Tier rewards that scale
Buy 3, get 10%. Buy 5, get 15% and free shipping. Up to five tiers per bundle, applied automatically when the cart qualifies.
Real cart lines
No phantom bundle SKU, no inventory drift. Each picked item is its own cart line, attributed to the bundle for analytics.
Conflict guardrails
BigBox blocks conflicting active bundles on overlapping products, so one product page never serves two competing offers.
Drawer or inline
Run the builder as a pop-out drawer or an embedded section on the page. Both come from the same app block in the theme editor.
Per-bundle analytics
Funnel metrics from eligible views to paid orders, recomputed from real Shopify orders after webhooks.
Mix-and-match questions, answered.
What is a mix-and-match bundle?
A mix-and-match bundle lets shoppers combine any products they like from a set you define, instead of buying a fixed combination. With BigBox they mix and match on the product page and unlock tier rewards as they add items.
Can shoppers mix different variants?
Yes. Shoppers pick the exact variants they want, and you can restrict which variants are offered per bundle and hide out-of-stock items.
Do mixed bundles create duplicate products?
No. BigBox never creates a separate bundle product. Every selection is added to the cart as a real Shopify cart line with attribution properties, so inventory and reporting stay accurate.
How do discounts apply to a mixed cart?
Through Shopify automatic app discounts and Shopify Functions. When the cart qualifies for a tier, the discount applies at checkout automatically - no codes for shoppers to type.
Can I run mix-and-match on only some products?
Yes. You choose exactly which product pages carry the offer, and you can target by customer, customer tag, or market, and schedule when the bundle runs.
