A volume discount (also called a quantity break) drops the unit price as customers buy more — "1 for $20, 3 for $54, 5 for $85." It's a simple, honest way to reward bigger orders, move stock faster, and raise average order value without a sitewide sale.

When to use quantity breaks

  • Consumables customers stock up on — coffee, supplements, pet food.
  • Wholesale-leaning or bulk-friendly products.
  • Low-consideration add-ons where "buy a few" is natural.
  • Anywhere you'd rather sell 3 units at a small discount than 1 at full price.

How to structure your tiers

Keep it to two or three clear tiers so the choice is easy:

Buy 1  →  $20.00 each
Buy 3  →  $18.00 each  (save 10%)
Buy 5  →  $17.00 each  (save 15%)

Each step should feel like a real reward, but never below your cost — check the margin at each tier with ProfitVault before you launch.

How to set it up on Shopify

  1. Install Packmate and go to Bundles → Create bundle → Volume discount.
  2. Add your tiers — quantity thresholds and the discount at each.
  3. Turn on the widget so the tiers show on the product page with the savings.
  4. Publish — the right price applies automatically at checkout, no code.

Best practices

  • Show the per-unit price at each tier — shoppers respond to "$17 each," not just "15% off."
  • Anchor the top tier so the middle one looks like the smart choice.
  • Don't over-tier. Two or three steps convert better than six.
