Shopify quantity breaks without an app

Quantity breaks là gì?

A quantity break is a discount that gets larger as the customer buys more of the same product — buy three, save 10%. Hullara renders the tiers you configured as buttons on the product page; pressing one sets the quantity in the buy form, and Shopify applies the discount you set up in your admin.

The version of this feature that costs merchants money

Every quantity-break app, and most themes that ship one, does the same thing: takes the price, multiplies it by your percentage, and prints "£12.75 each" under the tier. It looks more helpful. It is the part we refuse to build.

A Shopify discount is not evaluated by the theme. It is evaluated at checkout, against conditions the product page cannot see:

which customer segment the shopper is in,
whether it combines with another discount they already have,
a minimum subtotal,
usage limits and start and end dates,
and whether you changed the percentage in your admin after typing a different one into the theme.

Any one of those makes the number on the page diverge from the number at the till. Both directions are bad and one is much worse: a page that promised less than the customer is charged is a chargeback, a support thread, and — in the UK and the EU — a price-indication problem that lands on the merchant.

What it does instead

It restates your offer, sets the quantity, and lets the cart be where money is stated.

The tiers you type are a description of a discount you have already created in Settings → Discounts. Pressing one writes the quantity into the product form — the same single input the quantity stepper uses, so there is never a second number in the page disagreeing with the first — and it writes it in a way the form's own validation sees, so a tier your variant's rules forbid gets corrected instead of travelling to the cart as a quantity you cannot sell.

Then the saving appears in the cart, where it comes from cart.items[].line_level_discount_allocations — Shopify's own answer to what this order is actually being discounted by. The loop closes on a fact rather than on an estimate.

What that costs you, said plainly

A shopper reading the product page sees the offer and the quantity, and does not see the per-unit price until the cart. Some merchants will want that number on the page. It is a real preference and this theme will not serve it.

The alternative is a number that is right most of the time. We would rather ship the version that is right every time and say why, than the version that demos better.

You still need to create the discount

Nothing here creates one. This is a display for an automatic discount that must already exist in your admin, and the theme setting says so at the point where you type the tiers.

That is deliberate too: a theme that created discounts would be a theme holding your pricing, and the day you edit that pricing anywhere else the two copies disagree. Shopify owns your discounts. This owns the way they are explained.

Which edition

Pro. Core has the product page, the quantity stepper and the cart that states the saving — the tier ladder is one of the sections and blocks that make up the difference between the two downloads. The pricing page lists exactly which artefacts each edition contains, generated from the theme's own build.

Những câu người ta thật sự hỏi

Do I need an app for quantity breaks on Shopify?

Not for showing them. Shopify already applies volume discounts through automatic discounts in your admin; what most themes lack is anywhere on the product page to say so, which is the gap the apps fill. Hullara has the surface built in, so the discount stays Shopify's and only the display is the theme's.

Why does it not show me the discounted price per item?

Because the theme cannot know it. Shopify evaluates a discount at checkout against things no theme can see — customer segment, combination rules with other discounts, minimum subtotal, usage limits, start and end dates, and whether you changed the percentage in the admin after typing a different one into the theme. A figure computed here can disagree with the till, and a page that promised less than the customer is charged is the worst version of that. The saving appears in the cart, from Shopify's own line-level discount data.

Does the block create the discount?

No. The tiers describe a discount that has to exist already, as an automatic discount in Settings → Discounts. The theme setting says so where you type them. A tier list with no discount behind it is a promise your checkout will not keep.

What happens when a customer presses a tier?

It sets the quantity in the product form — the same input the quantity stepper writes to, not a second hidden one — and it does it in a way the form's own clamping sees, so a tier your variant's rules forbid is corrected rather than carried through to the cart.

Which edition has it?

Pro. Core ships the product page, the quantity stepper and the cart that states the saving; the tier ladder itself is one of the sections and blocks that make up the difference between the two downloads.
