Volume discount bundles don't use this list at all — every option in a Volume discount is priced independently (see "Volume discount options," below).

Yes, but only when the number of items the bundle can end up containing is fixed. Percentage is always offered. Sale price and Amount off appear only once the item count is bounded — either nothing lets the shopper change it (Optional products and the Quantity selector both off), you've capped it with Maximum items allowed set to Limited, or you're pricing product-by-product with Applies to set to Individual product price and the Quantity selector off. The exact combinations that unlock each type are covered in "Choosing a discount type for your bundle" — the rule above is the short version.

One method removes the choice entirely: with the Free gift discount group on, there's no discount type to pick at all — the whole Applies to / Type / Value grid disappears, replaced by "Free" tick boxes on individual products.

It depends on what's being counted:

No. Every free-gift mechanism needs you to name the products, variants or collections in advance. There is no rule that finds whichever item happens to be cheapest in a shopper's selection and discounts it.

No. There is no per-customer limit, on purchases or on discounted units. Each checkout is evaluated on its own, with no memory of that customer's earlier orders.

No. The Combinations settings are set once per store, in Settings, and apply to every bundle equally. They work by discount class — Product, Order, Shipping, Subscription — not by individual code, so you cannot let one influencer's code stack while blocking another's.

The app's discount engine only ever issues product discounts; it never touches shipping. Whether your free-shipping threshold is measured before or after the bundle discount is Shopify's own behaviour, not something this app sets or changes.

No. Sale price can only lower the bundle's total. If the products a customer selects already cost less than the sale price you set, the bundle is added to the cart at the real product price instead — the app never charges more than the components would normally cost.

Each option in a Volume discount can carry:

Options are constrained so the ladder always makes sense: Required items must exceed the previous option by at least one; once an option discounts, every option after it must also discount; and values must move in one direction across options — percentage and amount-off values increase, sale prices decrease. You can't build a Volume discount where a later, higher-quantity tier is worse than an earlier one.

Full field-by-field mechanics are in "Discount options, tiers and add-ons."

Three separate mechanisms, all optional for the customer to accept.

Auto-add free gift to cart (an Advanced setting) controls whether the reward lands in the cart automatically:

No. Bundle discounts are automatic: they are calculated by Shopify at the cart and applied without anyone typing a code, so there is no code to make unique. The app cannot generate a per-customer code — for a free gift, a member reward, or anything else. If your campaign depends on each customer receiving their own code, that belongs in Shopify's own discount tools or a dedicated app, not here.

To each product's own price in the cart, not to a single pooled bundle total. Every product in the qualifying bundle is discounted by the same percentage off its individual price. With products at different prices, the more expensive ones give up more money, and the total taken off still equals that percentage of the combined subtotal.

Yes, within limits you control. Combinations discounts in the app's settings gives you four store-wide toggles — Product, Order, Shipping, Subscription — that each permit Shopify to consider combining the bundle discount with that class of Shopify's own discount, subject to Shopify's own combination rules. These toggles don't change any individual bundle's discount; they control what's allowed store-wide.

What isn't established anywhere in the app's documentation is how a bundle discount interacts with a third-party app's own automatic discount — specifically whether two automatic discounts compound, which one wins, or in what order they're applied. If you're running another app's automatic discount alongside a bundle and need to know the exact interaction, that's a case to bring to support directly rather than infer from the toggles above — mention which combination toggle you have on and the name of the other app's discount so support can check it for your store.

Shopify limits how many active automatic discounts a store can run at once. Bundles beyond that ceiling simply stop discounting, and the app's bundle list shows a warning banner when this happens. See "Plans, billing and limits" for the other numeric caps that apply to bundles.
