Bundle discounts that don’t break print-on-demand fulfilment. A Shopify app by SatoriSoul.

The problem it solves

Most bundle apps create a merge product: the three shirts your customer picked become one line called “Summer Bundle”. Your fulfilment partner receives that line and has no idea which garment, which size, which print file. Somebody has to unpick it by hand, or the wrong thing gets printed.

Printline Bundles applies its discount to the real line items in the cart. Each garment keeps its own line, its own price and its own discount. The order reaches Printful, Printify, Gelato, podOS or any other service exactly as the customer placed it.

What it does

• Quantity tiers per product type. Buy 2 and save 10%, buy 3 and save 15% — as many steps as you like. Quantities count across every matching line, so three different sizes of the same product type count as three.
• One discount, several product types. Shirts and hoodies can run side by side in the same rule, each counting independently.
• 20 banner designs for the cart, product pages and store-wide. Each one updates live and shows how many more items are needed for the next tier — rendered by Shopify at page build, so there is no flicker and no JavaScript.
• No merge product, ever. That is the whole point.

Who is behind it

SatoriSoul is a print-on-demand shop. We sell our own designs on shirts and hoodies, and we hit this problem ourselves: every bundle app we tried either broke the production files or forced us to choose between a working discount and a working order.

So we built the app we needed, then made it configurable enough for other shops. It is maintained by the same person who runs the shop — which means support answers come from someone who has actually shipped print-on-demand orders, not from a ticket queue.

When you write in, include your shop domain and the name of the discount if one is misbehaving. That is usually enough to reproduce it straight away.
