+Offer promotional pricing only for specific bundle sizes.
+
+**Example:**
+- Holiday Bundle: 12 units (seasonal pricing)
+- Party Pack: 24 units (bulk discount)
+- Wholesale Bundle: 100 units (wholesale pricing)
+
+## Configuration Examples
+
+### Example 1: Site-Wide Restriction
+
+**Scenario:** All products should only be sold in packages
+
+**Configuration:**
+1. Go to WooCommerce > Settings > Tier & Package Prices
+2. Check "Restrict to Package Quantities"
+3. Save changes
+4. Configure package sizes for each product
+
+**Result:** All products with packages defined will enforce quantity restrictions
+
+### Example 2: Per-Product Restriction
+
+**Scenario:** Only specific products need quantity restrictions
+
+**Configuration:**
+1. Leave global setting unchecked
+2. Edit the specific product
+3. Scroll to Package Pricing section
+4. Check "Restrict to Package Quantities"
+5. Update product
+
+**Result:** Only that product enforces restrictions
+
+### Example 3: Mixed Approach
+
+**Scenario:** Most products are restricted, but some allow custom quantities
+
+**Configuration:**
+1. Enable global restriction
+2. For products that should allow custom quantities, simply don't define any packages
+3. Products without packages defined won't show restrictions
+

+
+### Scenario 2: Mixed Catalog
+Some products restricted, others not. Shop page shows appropriate buttons.
+
+**Customer Experience:**

+

magdev	4ece4dd69e	Release version 1.1.2 - Catalog button modification Enhanced package quantity restriction enforcement by replacing "Add to Cart" buttons with "View Options" links on catalog pages for products with quantity restrictions.

magdev	3e06137559	Release version 1.1.1 - Cart quantity field hiding Enhanced package quantity restriction enforcement by hiding the cart quantity input field when restrictions are enabled. This prevents customers from modifying quantities in the cart to bypass package restrictions. Changes: - Added cart quantity input hiding for restricted products - Implemented woocommerce_cart_item_quantity filter hook - Created maybe_hide_cart_quantity_input() method in WC_TPP_Cart - Fixed cart quantity bypass vulnerability - Cart displays quantity as read-only text for restricted products 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>	2025-12-21 17:21:40 +01:00

Features: - Global setting to enable package quantity restrictions - Per-product override for quantity restrictions - Automatic hiding of quantity input field when restricted - Frontend validation with package selection UI - Server-side cart validation - User-friendly error messages - Complete translations for all supported languages 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>	2025-12-21 15:54:04 +01:00
