What BigBox does

BigBox adds a build-your-own-bundle offer to your Shopify product pages. Instead of buying a single item, customers pick several products, see their savings grow as they add more, and add everything to the cart in one step.

What your customers see

On a product page where you have set up a bundle, customers get a button such as “Build your bundle”. Opening it shows the products they can choose from, with quantity controls and a running summary of their subtotal and savings. When they have what they want, they add the whole selection to the cart.

Real cart lines, no separate product

Every item a customer picks is added as a normal Shopify cart line. There is no separate “bundle product” to create or keep in inventory sync. Each line carries a small BigBox tag so you can see later which orders came from a bundle.

Rewards that grow with the cart

You set up reward tiers, for example “Buy 3 and save 10 percent” or “Buy 5 for free shipping”. As a customer adds items, BigBox shows how close they are to the next reward, and the discount applies automatically at checkout once the cart qualifies.

What you control

From the BigBox admin you decide:

• Which products or collections customers can choose from.
• The smallest and largest number of items a customer can pick.
• The reward tiers and how much each one saves.
• Where the offer appears and how it looks.
• Who is eligible to see it.

The rest of this help center walks through each of these in detail. A good place to start is installing BigBox and adding it to your theme.
