Shopify Bundles is the right choice when the bundle is a product of its own.
It is free and made by Shopify. If one of these describes your store and you need nothing else, install it and keep your money.
You sell a kit as one item
A gift box or starter set with its own photos, its own page and its own place in your collections.
You also sell in person
Shopify Bundles works in Shopify POS. TreStack Bundles does nothing special for POS.
You want the stock worked out for you
Shopify counts how many bundles you can sell from the product inside with the least stock.
You need no tiers, gifts or mix and match
Then a free app made by Shopify is the sensible choice, and a paid deals app would be money spent on nothing.
When TreStack Bundles fits better.
When the offer belongs on a product people already visit, and the answers to the questions that come next.
When is TreStack Bundles the better choice?
When the offer belongs on a product people already visit: Buy 2, save 15%, buy one get one, a free gift at three, a set the shopper builds, or a subscribe option next to the tiers.
It also suits a store that wants to test offers. Each deal can run an A/B test with up to 4 variants, and the app reports the added revenue of every deal.
Does TreStack Bundles create bundle products?
No. A deal sits on products you already have, and each item reaches the cart as itself. A complete mix and match set is merged into one cart line when Shopify allows it.
The app does create one hidden product for each mix and match bar and each personalisation fee. Those stay in your product list after an uninstall, and you can delete them yourself.
Can I run both apps on one store?
We have not tested TreStack Bundles next to Shopify Bundles. If you try it, keep each product in one app only, and place a test order before you publish a deal.
What does a store need for Shopify Bundles?
Shopify's help center says the store must use the Online Store channel or a custom storefront, and that stores with checkout.liquid customizations cannot use product bundles.
What does a store need for TreStack Bundles?
A theme where you can turn on the app embed in the theme editor. The widget places itself above the Add to cart button, and no theme files are edited. It is verified on Horizon and Dawn.
