Install Omake from the Shopify App Store and choose a plan.

• Free: 1 gift rule with 1 condition
• Pro: $3.99/month, with a 14-day free trial

You can change plans at any time.

Add the gift to Shopify like any other product.

• Set the price to ¥0: it shows as "¥0" in the cart
• Check "Online Store" under sales channels: otherwise it can't be added to the cart

You can also show the original price struck through, discounted to ¥0. See the FAQ.

In Omake's "Gift rules", click "Add a gift rule", set these two things, and save.

• Condition: for example, "cart total is 10,000 or more"
• Gift product: the product from step 2

See more condition examples in What Omake can do.

This is the switch that shows banners and gifts in your store.

Click the link in the "Setup guide" at the top of Omake to open the theme editor (where you edit your store's look). Turn on "Omake gift auto-add" and save. No theme code changes are needed.

Once every item in the setup guide says "Complete", you're ready.

Add products to your cart and check that the gift is added (or offered) once the cart qualifies.

If you remove items so the cart no longer qualifies, the gift is removed automatically.

If something doesn't show up, see the FAQ.
