Each tier of a volume discount can come with free gifts. To add one, click Bundles & Discounts in the app, open a volume discount, click Discount tiers in the steps on the left (step 2), and click the gift button next to the star on a tier. Until a tier has a gift, Free gift under Add to this offer on the left opens the same tiers. When shoppers add the tier, its gifts are added too, and they're free at checkout while the cart stays at that tier. To create the offer itself, see the guide on creating a volume discount.
What this video covers
With Add a gift product, you pick the gift. With Let shoppers choose gifts, shoppers pick from products you choose.
Add a gift product opens the product list. Change swaps the gift for another product, and Quantity sets how many come free. Only as a one-time purchase adds the gift without a subscription, even when shoppers subscribe to the tier; left off, the gift joins their subscription when the gift product offers the same plan. Show the full price crossed out shows the gift's regular price on its line. Shows as is the wording of that line, and Edit texts opens it on the Design tab, where a variable can add the gift's name.
Add a gift product again adds another gift, and you can drag gifts to reorder them. With two or more gifts, When this tier has several gifts appears. Give every gift adds them all. Shoppers pick one variant of each gift is for a gift you added in several variants, like sizes: shoppers choose one from a drop-down. Shoppers pick one gift puts all the gifts in one drop-down, and shoppers get the one they pick.
Let shoppers choose gifts adds the card Gifts shoppers choose. Shoppers pick their gifts in a pop-up, and up to the number you set are free at checkout. Add gifts to choose from picks the products they choose between, and Remove takes one out. How many shoppers can choose sets how many are free. Show photos of the chosen gifts puts their photos on the tier once picked, and Show the full price crossed out works as before. Edit texts on the card covers the row's wording and the pop-up's title. In Try it, the row under the gifts opens the pop-up: shoppers click Choose, then Confirm.
The three dots on a gift remove it. Once a tier has a gift, the tier row shows it, like + Decaf Coffee (or + 2 gifts), and its gift button is filled in.
If a lower tier saves more than this one, the Free gifts window warns that the gift won't be free, and says how to fix it.
Below the tiers, Add tier gifts to carts automatically appears once any tier has a gift. It's one setting for every tier, and it's off until you turn it on. Off, gifts are added when shoppers add a tier with the offer's widget. On, a cart that reaches a tier with gifts gets them even when items were added another way, like the cart page or your theme's button.
On your store: after Save, give it a few seconds to go live. On the product page, tier 2 shows the gift under its price, with the full price crossed out. With 2 items added to the cart, the cart has two bags at the discount and Decaf Coffee at $0.00.
In short
Gifts show only in the Modern widget. On an offer that uses the Legacy widget, the Free gifts window says to switch to the Modern widget in Look.
A gift is free while the cart stays at its tier. If a lower tier saves more, the window warns that the gift won't be free.
Leave Only as a one-time purchase off for a gift product that's sold only on a subscription: as a one-time gift it fails at checkout when shoppers subscribe, and the window warns you.
Add tier gifts to carts automatically is one setting for every tier, and it's off until you turn it on.
