How can I create product bundle discounts in my online store?

Topic summary

Implementing fixed-price mix-and-match bundle discounts (e.g., 6 for £20, 3 for £25) across a defined set/collection, with a banner on relevant product pages linking to all eligible products. Percentage discounts aren’t suitable because individual item prices vary.

Suggestions offered:

  • BYOB app: lets shoppers pick x products from a collection for a fixed price; creates a standalone bundle product page with a top banner; a sample bundle link was shared.
  • Bundler and Bundle Product Volume Discount apps (from Shopify staff): support fixed discounts, fixed amounts, or fixed total price bundles; can display banners and recommend bundle products/collections; guidance to use trials, read reviews, and uninstall before charges.

Latest clarification: The merchant sells two brands (items at £8.99 and £9.99) and wants “3 for £25” with full mix-and-match. There are too many combinations to prebuild bundles.

Key requirement: An app that automatically detects when 3 items from the set are in the cart and applies a fixed total of £25 at checkout.

Outcome: No solution identified yet; the thread remains open with the merchant still seeking an app that applies cart-level fixed-price bundles.

Hi!

Unfortunately, no I have not found a solution.

The best example is that I sell two brands, each with 50 plus individual products. Brand A is £8.99 or 3 for £25, Brand B is £9.99 or 3 for £25. I want to be able to mix and match but there are too many possible variations to do so as a bundle.

I need an app that will recognise there are 3 products in the cart from a set list and then apply the discount so the total sum of the 3 products is £25.

In my head this should be so simple, but as of yet can still not find a way to do it!
