BigBoxTiered discounts that pull bigger carts
Buy 3, get 10%. Buy 5, get 15% and free shipping. BigBox puts the tiers on the product page with a progress bar shoppers actually watch, and applies the discount automatically at checkout through Shopify Functions. Average order value does the rest.

Volume incentives in three steps.
Set the ladder
Define up to five quantity tiers. Each tier can reward a percentage discount, a fixed discount, a free gift, or free shipping.
Show the progress
Shoppers see numbered tier nodes and a progress bar as they build their box, so the next reward is always one or two items away.
Apply it at checkout
When the cart qualifies, the discount applies automatically as a Shopify automatic app discount. No codes, no cart scripts, no draft orders.
Built to raise average order value.
The mechanics behind buy-more-save-more, without the operational mess.
Five-tier ladders
Mix reward types across tiers: discounts early, a free gift in the middle, free shipping at the top.
Native discounting
Discounts run through Shopify Functions with Shopify-resolved product, variant, customer, and market context.
Real cart lines
Tier math runs on real Shopify cart lines with attribution properties, not on a synthetic bundle product.
Targeted and scheduled
Run tiers for everyone, for specific customers or tags, or per market, and schedule when the offer is live.
Conflict-proof
Overlapping active bundles on the same products are blocked, so tiers never stack in ways you did not plan.
Tier-level proof
Funnel and paid-order analytics show whether the ladder actually moves order size, per bundle.
Tiered discount questions, answered.
What are tiered quantity discounts?
Discounts that grow as shoppers add more items: buy 3 for 10% off, buy 5 for 15% off. With BigBox the tiers live inside a bundle offer on the product page, with a progress bar showing shoppers how close they are to the next reward.
How are the discounts applied?
Through Shopify automatic app discounts and Shopify Functions, using Shopify-resolved product, variant, customer, and market context. The discount applies at checkout whenever the cart qualifies.
How many tiers can one bundle have?
Up to five quantity-based tiers per bundle. Each tier rewards shoppers with a percentage or fixed discount, a free gift, or free shipping.
What stops two offers from stacking on one product?
BigBox blocks conflicting active bundles on overlapping active products when their eligibility scopes overlap, so one product page never serves two competing offers.
What happens if the connected discount breaks?
The bundle editor checks whether the connected Shopify discount exists and is active. If it's missing, expired, or invalid, you get a one-click repair, and discount webhooks attempt recovery automatically.
