Volume Discount — quantity-tier discounts on the product page

Offer tier-based discounts directly on the product page — buy more, save more — with subscription discounts stacking on top. No more quick-checkout-link workarounds or hidden-widget tricks.

How it works

• A new plan type, Volume Discount, in Selling plans → New plan. Define quantity tiers — minimum/maximum quantity, the discount, and a label — and optional billing intervals.
• The storefront widget shows the tiers along a savings track with each tier's discount and a live subtotal. Your theme's native quantity stepper stays in sync with the selected tier.
• At checkout the tier discount is applied automatically to the right line — the rest of the cart is untouched. Below the smallest tier minimum, no discount applies.
• When the customer also picks a recurring frequency, the subscription discount stacks on top of the tier discount.
• If a product is covered by both a regular subscription plan and a Volume Discount plan, the Volume Discount widget takes over on that product page so customers see one clear offer.
