Quantity Discounts
Quantity discounts incentivise customers to buy more units per order by offering a lower per-unit price at higher quantities. They increase average order value and reduce fulfilment costs per unit sold.
What is Quantity Discounts?
Quantity discounts (also called tiered pricing or volume discounts) structure pricing so that buying more units reduces the effective price per unit. A common structure: 1 unit at $24.99, 2 units at $21.99 each, 3+ units at $18.99 each. The discount is presented on the product page as a visual tier — clearly showing the savings incentive for buying more.
For ecommerce brands, quantity discounts serve multiple purposes: they increase AOV by incentivising multi-unit purchases; they reduce per-order fulfilment cost (packing and shipping 3 units in one box costs roughly the same as shipping 1 unit); they can increase repurchase interval (a customer who buys 3 units won't need to reorder for 3× as long, but their LTV is higher and retention probability improves).
On Amazon, quantity discounts are implemented through Business Pricing for B2B buyers, or through Quantity Discount promotions (formerly Tiered Coupons) for consumer products. On Shopify, apps like Bold Quantity Breaks or Shopify's native discount system allow flexible tiered pricing structures.
Why it matters for sellers
Every additional unit in an order improves economics without proportional cost increases. If your average order is 1.3 units at $24.99 ($32.49 AOV) and quantity discounts shift it to 1.8 units at $22.50 average ($40.50 AOV), revenue per order increases 25% while fulfilment cost per order increases less than 10%. This leverage directly improves both gross margin and LTV without requiring additional customer acquisition.
How to use Quantity Discounts
Analyse your current order distribution. If 85% of orders are single-unit, a quantity discount is likely to shift a meaningful portion to 2-unit orders. Set your quantity break threshold at 2 units first — this is where most AOV lift comes from. Ensure the per-unit discount at 2 units is at least 15% to make the value proposition compelling.
On product pages, display the quantity discount table visually with a 'Savings' column. Highlight the 2-unit or 3-unit option as 'Most Popular' or 'Best Value'. Add urgency language: 'Save more, stock up'. For consumables (protein powder, skincare, supplements), frame multi-unit purchase as 'Never run out again'.
Real-world example
A skincare brand selling a $32 moisturiser has 78% single-unit orders. They implement a quantity discount: 1 for $32, 2 for $56 ($28 each, 12.5% saving), 3 for $78 ($26 each, 18.75% saving). Within 60 days, single-unit orders drop to 54%, 2-unit orders rise to 35%, 3-unit to 11%. AOV shifts from $32 to $44.20. Monthly revenue increases 38% with zero increase in customer acquisition spend.

Frequently asked questions about Quantity Discounts
What discount percentage makes quantity discounts effective?
10–20% per-unit savings at the 2-unit tier is the typical effective range for consumer products. Below 10%, customers don't feel the incentive is worth committing to a multi-unit purchase. Above 25%, you may be eroding margin faster than the AOV benefit compensates. Test 15% at the 2-unit tier first, then optimise based on conversion data.
Do quantity discounts work on Amazon for consumer products?
Yes, but the implementation differs from Shopify. On Amazon, use the 'Quantity Discount' promotion under Promotions in Seller Central. You can set tiered discounts visible on the product detail page. These work well for replenishable consumables. For B2B buyers specifically, Amazon Business Pricing has a dedicated quantity pricing table shown only to Business customers.
Won't quantity discounts reduce my revenue per unit?
Yes, per-unit revenue decreases — but total order revenue and margin per order increase when customers buy more units than they would have at full price. The test is whether the AOV increase exceeds the per-unit margin reduction. If your margin is 60% and you offer 15% off, your margin on incremental units drops to ~53% — but you've turned a $32 order into a $56 order. The net effect is almost always positive for AOV-sensitive metrics like ROAS and LTV.
