Rules are evaluated automatically at cart/checkout — no coupon code needed. **Discount Types:** * **Percentage** — e.g. “10% off the entire cart” * **Fixed Amount** — e.g. “₹100 off cart” * **Buy X Get Y** — e.g. “Buy 2, get 1 free” (cheapest eligible items are discounted) **Conditions (can be combined):** * Minimum cart spend * User role (customer, wholesale, subscriber, etc.) * Product category slug present in cart * Day(s) of the week (time-based deals like weekend sales) **Rule Control:** * Priority system — only the highest-priority matching rule fires (no stacking) * Enable / disable rules without deleting them * Delete rules permanently The discount appears as a cart fee line item with the rule name as its label, keeping the cart transparent to customers. ### Usage Examples **Weekend 15% sale for all users:** * Type: Percentage | Value: 15 * Conditions Days: Saturday, Sunday **₹500 spend ₹50 off for Wholesale customers:** * Type: Fixed | Value: 50 * Min Spend: 500 | Conditions Role: wholesale_customer **Buy 2 T-shirts, get 1 free (cheapest):** * Type: Buy X Get Y | Buy: 2 | Get: 1 * Conditions Category: t-shirts ### How Buy X Get Y Works The Buy X Get Y rule uses a **group-based algorithm** that always gives the cheapest qualifying items for free. **Algorithm (step by step):** 1. All items in the cart are flattened into individual unit prices. e.g. Cart: 2× T-shirt @ ₹200, 1× Jeans @ ₹800, 1× Cap @ ₹150 unit prices: [200, 200, 800, 150] 2. Prices are sorted cheapest-first: [150, 200, 200, 800] 3. The number of complete qualifying groups is calculated: group size = Buy + Get = 3 + 1 = 4 total items = 4 floor(4 ÷ 4) = **1 group qualifies** 4. For each group, the cheapest `Get` items are free: ₹150 (cap) is free discount applied = **−₹150** The discount is added as a negative cart fee line item labelled with the rule name, keeping the breakdown transparent to customers. **Why cheapest-first?** This prevents customers from gaming the rule by adding one cheap item to get an expensive item free. The cheapest item always fills the free slot. **Only complete groups qualify:** With Buy 2 Get 1 and 5 items in the cart: floor(5 ÷ 3) = 1 complete group 1 item free (the cheapest) The leftover 2 items do not form a group and get no discount. **Configuration examples:** * Buy 1 Get 1 Free Buy: 1, Get: 1 * Buy 2 Get 1 Free Buy: 2, Get: 1 * Buy 3 Get 2 Free Buy: 3, Get: 2 * Buy 4 Get 1 Free (BOGO4) Buy: 4, Get: 1 Combine with a **Product Category** condition to restrict the rule to specific product lines (e.g. only T-shirts, only Electronics). ## Installation 1.
