Limiting a discount to an exact quantity (strict quantity cap)

Limit discount to offer quantity in Bundlex Bundles caps eligible quantity offers instead of discounting every qualifying unit. Each distinct discounting tier can apply at most once within the qualifying group. Units left over stay at full price.

How the cap changes a quantity offer

Suppose your only discounting tier is "Buy 3, save 15%":

Buying twice the tier quantity does not repeat that tier when the cap is on.

Using several tiers

Bundlex Bundles can combine eligible tiers, using each at most once. With "Buy 3, save 15%" and "Buy 5, save 25%", a quantity of 8 can receive 25% off 5 units and 15% off 3 units. At quantity 10, the remaining 2 units stay full price.

Offers with no discount do not add to the cap. Offers with the same quantity threshold are alternatives, not extra allowances you can add together. The combination used depends on the qualifying quantities and savings.

For a $28 USD face cream with those two tiers, the cart and checkout product totals are:

Shipping is separate. The eight-unit allowance comes from 5 plus 3, not just the largest tier of 5.

Which offer types it affects

• Percentage and Amount off per item: eligible quantity tiers use the each-tier-once rule.
• Fixed total price: the rule also applies when the qualifying units have the same price. Mixed-price groups use the normal exact-price calculation instead.
• Buy X, get Y: uses its own buy-and-get calculation, rather than combining tiers with this rule.
• Product bundles with required paid products: keep their bundle-completeness checks. They do not use the quantity-tier combination described above.
• None: there is no main-product discount to cap.

Turn on the cap

1. Open the bundle deal in Bundlex Bundles.
2. Open the Advanced tab.
3. In Discount rules, enable Limit discount to offer quantity.
4. Save and activate the deal. Test a qualifying quantity and a quantity above the cap in the cart and checkout.

The setting is off by default and applies to the discount as a whole.

The Bundlex Bundles Quantity selector cannot be enabled while this cap is on. Shoppers can still change quantities in the theme's cart, so verify that path as well.

Free gifts with capped tiers

A selected tier's gift entitlement does not repeat just because the shopper adds more units. With a single "Buy 3 + one gift" discounting tier and the cap on, quantity 6 qualifies for 3 discounted main units and one gift, not two. The other 3 main units stay full price.

The selected tier must be part of the applied tier combination for its gift to qualify. Combining main-product discounts from several tiers does not automatically add gifts from tiers the shopper did not select.

Why some units stay full price

Cart and checkout can show separate discounted and full-price quantities. With the cap on, this is expected once the eligible tier allowances are used. Turn the cap off if you want a percentage or per-item offer to discount every qualifying unit above its threshold.

If the cap is off and the total is still unexpected, check required bundle products and other active discounts. See combining discounts. Cart and checkout determine the final amount paid, including rounding.

Check the result before launch

• Test one tier, a combination of tiers and a quantity above their total allowance.
• Reduce the cart below the first discounting tier and confirm full-price units return.
• Compare the cart and checkout quantities, line discounts and product subtotal.
• If an offer includes gifts, test their quantities separately. A main-product cap check does not verify every gift setup.
