Galantis Discount Flow does its pricing work at checkout through a Shopify discount Function — that part needs no theme changes at all. The storefront side is different: auto-adding free-gift items to the cart and showing customer-facing signals is handled by a theme app embed, and Shopify requires you to switch app embeds on yourself. Enabling it takes under a minute in the theme editor, and there is no theme code to touch.
Without the embed enabled, Free gift auto-add and storefront signals do not work — a Free gift campaign can’t place the gift in the cart, and customers get no on-page cues. Price discounts (percentage, fixed amount, shipping, and so on) are still applied at checkout by the discount Function regardless.

Embed settings explained

Default: on. The master switch for all storefront behavior. Turn it off to pause everything the embed does — free-gift auto-add and storefront signals — without uninstalling the app. Checkout pricing is unaffected either way.
Default: off. Intended for troubleshooting during setup. Leave it off in normal operation; switch it on only when you’re investigating storefront behavior with support.
Default: on. When a customer’s cart qualifies for a Free gift campaign, the embed automatically adds the gift item to the cart. Turn this off if you don’t want gifts added automatically — but note that Free gift campaigns rely on this behavior to deliver the gift.
Default: on. Displays a storefront notification the moment a free gift lands in the cart, so customers understand why a new item appeared. Turn it off for a silent auto-add.
Default: “Your free gift has been added to your cart 🎁”. The message shown by the notification above. Edit it to match your brand voice or language.

​
When the embed is required — and when it isn’t

Even if you only run price discounts today, enable the embed anyway. It costs nothing, and your first Free gift campaign will work on day one instead of failing quietly because the embed was never switched on.
