Auto-add a free gift with purchase when the cart hits a spend goal
Auto-adding a free gift with purchase isn't something Shopify's native Buy X Get Y does today, customers have to notice the offer and add it to their cart by hand. Stackable is building the automatic add and remove, so the gift appears and disappears with the cart total. Ships shortly after launch.

Merchants on the Shopify forums ask...
“How do I automatically add a free gift once the cart reaches a spend threshold, without a third-party workaround? Native Buy X Get Y exists, but it never adds the gift itself, the customer has to find it and add it manually, and most don't.”
A gift-with-purchase promotion only works as an incentive if the customer actually sees it happen. When the gift requires a manual add, most shoppers never notice the offer, and the ones who do have to leave checkout, find the gift product, and add it themselves, exactly where cart abandonment happens.
How Stackable solves it
Screenshot coming soon
Set the spend threshold and gift product
Pick any product as the gift and the cart-value trigger that unlocks it.
Screenshot coming soon
The gift will add itself automatically
Once the cart crosses the threshold, the gift line item will appear at $0, no customer action required.

It'll be removed automatically too
If the cart drops back under the threshold, the gift is removed the same way, so carts never keep a gift they no longer qualify for.
Use it like this
A fashion brand wants every order over $75 to include a free tote bag automatically.
Planned: threshold = $75 cart subtotal, gift = tote product, auto add/remove on.
A cart crossing $75 will show the tote at $0 without the customer doing anything; dropping back under $75 will remove it automatically.
A skincare brand wants a sample at $50 and a full-size gift at $100.
Planned: two thresholds pointing at two different gift products, only the higher-tier gift shown once both qualify.
Crossing $100 will show the full-size gift instead of the sample, not both at once, matching the intent of the promotion.
A coffee roaster wants the free-gift offer to apply only when $75 is spent within one collection, not sitewide.
Planned: threshold scoped to a collection subtotal rather than the full cart.
Only spend within the qualifying collection will count toward the $75, so unrelated add-ons won't unlock the gift.
Common questions
Is the free gift feature available now?
Not yet. It's in active development and planned to ship shortly after launch. This page describes exactly how it will work.
Will the gift really add itself with no customer action?
Yes, that's the point of the feature: the gift will appear as a $0 line item automatically once the cart qualifies, and be removed automatically if the cart drops back under the threshold.
Can I limit the gift to specific collections or customers?
The first release is planned to support cart-value thresholds scoped to a collection. Broader customer-segment targeting is a likely follow-up, not guaranteed for the first release.
Can I request early access?
Install the app and follow the changelog. Coming-soon features get flagged there as soon as they are available to turn on.

Discount Stacking
How to stack discounts in Shopify comes down to settings the platform hides by default: every discount belongs to a class (product, order, or shipping), and whether two discounts combine is decided per offer, per class. Stackable puts those combine switches on every offer, so a volume tier, a spend goal, and free shipping add up exactly the way you configured them, every time.
Bundles
Fixed-price Shopify bundles today mean a static bundle product: a fixed list of specific variants at a fixed price that breaks the moment your catalog changes. Stackable is building bundles that stay in sync with the collections and tags that define them instead. Ships shortly after launch.
BOGO / Buy X Get Y
Running BOGO beyond the 100-product cap isn't possible with Shopify's native Buy X Get Y discount: it stops letting you add eligible products once you pass 100, and it only applies once per order. Stackable removes both limits and adds cheapest-item-free logic on top.
Install Stackable and start with Free Gift
Every offer type runs on the same server-side engine, so whatever you combine, the checkout math holds.
