Check 8 / 21 LOW impact In the full checklist
Quantity selector + tiered bundle discount
What this check is
A quantity selector is a nudge to buy more; a tiered discount is a reason to. Together they move the average order value without a sitewide promotion.
How to implement it
Add a quantity selector on the product page, create automatic discounts for 2, 3 and 5 units, and show the tier prices next to the selector so the saving is visible before the cart. Keep the tiers profitable: set them from the unit margin rather than from a percentage you liked.
How to verify it
Select three units, add to cart and confirm the automatic discount applies with the tier price you advertised, and that the discount does not stack with a coupon that breaks the margin.
