How to set up a quantity discount on Shopify with Ladder
Choose a profitable quantity threshold, add Ladder’s product block and verify the saving at checkout. Includes Free-plan limits and how to stop an offer.
Choose a product people can use in multiples
Start with one variant where buying several makes sense, such as consumables or matching accessories. Ladder supports one qualifying quantity and one percentage saving per campaign. It is not a multi-tier table.
Calculate the offer before enabling it. For example, three $20 items with a 10% saving produce $54 in product revenue. If the items cost $30 in total, $24 remains before payment fees, packing, shipping, returns and other costs. This is an illustration, not a profit forecast.
Create the campaign and check its plan allowance
Open Ladder in Shopify admin. Under Campaigns, choose the product variant, minimum quantity and percentage discount. Save and activate the campaign so Shopify can create its matching checkout discount. Use a USD store.
Free includes 20 tracked interactions per calendar month. An interaction is an offer action before checkout, not a completed order. Growth costs $9 USD every 30 days and removes that monthly allowance. Both plans have a 100-campaign ceiling and no percentage or per-order app fee.
Place the offer in a duplicate theme
Duplicate your Online Store 2.0 theme for the first check. In its theme editor, open the product template and add Ladder’s app block near the purchase controls. In Ladder Appearance, enable Show on storefront and save.
Preview the configured product and variant on desktop and mobile. Check the quantity and saving shown, then use the offer to add the qualifying items to the cart. Save your theme changes before checking its storefront preview.
Verify the actual checkout
Test one item below the minimum, exactly the minimum and a larger quantity. Remove an item and change variants. Confirm that the eligible product receives the intended saving at checkout and that the other products retain their expected prices.
Try your usual discount codes too. Ladder’s quantity offer does not combine with other product or order discounts. Shopify checks the final discount; a visible offer or cart estimate is not proof that the final order qualifies. Resolve a mismatch before publishing the theme.
Stop the promotion deliberately
Pause the campaign in Ladder to remove its active discount. Hiding or removing the theme block alone does not end the checkout offer. Recheck checkout after pausing.
After launch, compare completed orders, item quantities, product margin and support questions. Separate changes in traffic and seasonality from the offer. Attributed sales do not establish that every sale was additional revenue.
