Demfilz Quantity Discounts for WooCommerce

Buy more, pay less. Set quantity tiers such as “10% off 5 or more, 15% off 10 or more” and the cart prices every line from the tier its quantity reaches. Customers see the tiers on the product page before they buy, and the cart tells them how many more to add for the next saving.

Three kinds of tier

• Percentage off each item: 5+ at 10% off, 10+ at 15% off.
• Amount off each item: 12+ at $1.50 off each.
• Fixed price per item: 1+ at $10.00, 10+ at $8.50, 50+ at $7.00. Ideal for wholesale price breaks.

Rules for the whole store, categories or products

• A rule covers all products, chosen categories (subcategories included) or chosen products and variations.
• Leave out individual products from any rule.
• Limit a rule to customer roles, for example wholesale customers only, or guests only.
• Schedule a rule with a start and end date.
• Priorities decide which rule wins when several cover the same product, or let the customer get the best price automatically. Discounts never stack.
• Duplicate, disable and re-enable rules from the list.

Per-product tiers

Every product gets a Quantity discounts tab. Use the store rules, set tiers for that product alone, or switch quantity discounts off for it.

Three ways to count quantity

• Per product: all variations of a product count together (2 small + 3 large shirts = 5 shirts).
• Per cart line: each variation counts on its own.
• Mix and match: every product a rule covers counts together, so “any 6 pairs of socks for 20% off” works across styles.

What customers see

• A pricing table on the product page (above or below the add to cart button, below the summary, or only where you place a shortcode) with the quantity ranges, the discount and the price per item.
• The row for the chosen quantity lights up and a live line shows the total and the saving as the quantity changes. Variable products fill in the prices when a variation is chosen.
• An optional “Buy more, save up to 20%” line under products on shop and category pages.
• In the cart, the original price struck through next to the discounted one, the discount under the item, and a hint such as “Add 3 more to pay $8.00 each”.

Correct everywhere

• Works with the classic cart and checkout and with the cart and checkout blocks, and in the mini cart.
• Prices are set on the cart line itself, so taxes, coupons, shipping and payment gateways all see the discounted price. There is no negative fee line.
• The discount is worked out from the product’s stored price, so plugins that adjust prices through WooCommerce’s price filters (currency converters, for example) apply on top of it exactly as they do on a normal price, and paid options added to a line by other extensions are kept.
• Unit prices are rounded to your store’s decimals, so quantity times unit price always equals the line total.
• Each order line records the discount it received, shown on the order screen, emails and invoices.
• Sale items: discount the sale price, discount the regular price and charge whichever is lower, or skip sale items.
• Compatible with WooCommerce High-Performance Order Storage (HPOS).
• No external services. Nothing leaves your site. Deactivate the plugin and your prices are untouched.
