Bundles: How discounts apply in Volume Discount bundles

Volume Discount bundles (“Buy More, Save More”) encourage customers to purchase higher quantities by offering tiered discounts.

Currently, discounts are applied based on the selection the customer makes when adding items to the cart.

How discounts are applied

• If a customer adds 1 item using the Buy 1 tier → no discount.
• If they then add 2 items using the Buy 2 tier → those two items receive the Buy 2 discount.
• The first item remains without a discount.

Even though the total quantity in the cart = 3, the system does not recalculate the discount to the Buy 3 tier.

Why this happens

Bundles processes discounts per batch (per click of “Add to Cart”), not by re-optimising the entire cart once items are combined.

This means:

• Discounts are accurate to what the customer selected at the time of adding.
• But mixed “batches” won’t automatically roll up into a higher tier.

Example

• Buy 1 item → $0 discount
• Buy 2 more items → 10% off those 2
• Cart = 3 items total → discount remains at 10% off 2 items, instead of 20% off all 3.

We’d love your feedback

We’re collecting feedback on how merchants prefer Volume Discounts to apply:

• Do you want discounts to always optimise automatically at the cart level?
• Do you prefer the current behaviour where discounts are applied based on each add-to-cart selection?
