About this plugin
Discount Rules Box adds a tiered “Buy Box” to your WooCommerce product pages — customers pick a 1, 2, or 3-pack quantity, see the exact price and savings for each option before adding to cart, and the discount is applied automatically at checkout. No coupon codes, no manual cart math, no page builder required.
Free gives you a fully working 2-pack buy box (1 & 2 pieces), automatic cart discounts, a live admin preview builder, all 4 pricing models, and every text/display toggle — this is a complete tool, not a crippled trial.
Pro (30-day free trial, no credit card) adds a 3rd pack tier, a Sales Analytics dashboard, full Appearance customization, product/category restrictions, and 1-Click language presets for 13+ languages.

PRICING MODELS AND FEATURES WITH EXAMPLE SCENARIOS
Free version features
- Discount on 2nd & 3rd Item — only the additional items are discounted, so the value is obvious. Example: $18 item, 40% off the 2nd → 1 piece $18, 2 pieces $28.80 ($14.40/unit).
- Discount on Entire Quantity — the same discount applies across every item in the pack. Example: 40% off both items in a 2-pack → $21.60 total ($10.80/unit).
- Percentage or fixed-amount discount, set independently per tier.
- Live admin preview builder — every color, text, and badge change updates instantly before you save.
- Compatible with Block Checkout, Classic Checkout, and WooCommerce High-Performance Order Storage (HPOS).
- [drbu_tiered_buy_box] shortcode for any page, or automatic replacement of the default “Add to cart” button.
- Manually edit every string (CTA buttons, badges, notes, shipping text) for full control over the copy.

Pro features
All Free features, plus:
- 3rd pack tier — add a “Buy 3” option with its own quantity and discount, e.g. 25% off the 3rd item on top of the 2nd-item discount.
- Fixed Total Package Price — Example: sell a 3-pack for a flat $39.99, regardless of the per-unit price.
- Fixed Price Per Unit — Example: price the 2-pack at exactly $14.40/unit, whatever total that produces.
- Sales Analytics dashboard — total upsell revenue, average-order-value lift, and sales share per tier, so you can see which pack is actually converting.
- Appearance customization — brand colors, button/card radius, and style presets, no CSS required.
- Product & category restrictions — run the buy box only on selected products or categories, e.g. Category A and Category B only, everything else untouched.
- 1-Click language presets — instantly fill every text, badge, and button field in 13+ languages; every field stays 100% editable afterward.
