- One-click package selection on product pages

### Admin Features

### Frontend Features

## Installation

1. Upload the `wc-tier-and-package-prices` folder to the `/wp-content/plugins/` directory
2. Activate the plugin through the 'Plugins' menu in WordPress
3. Make sure WooCommerce is installed and activated

## Configuration

### Global Settings

Navigate to **WooCommerce > Tier & Package Prices** to configure:

- **Enable Tier Pricing**: Turn on/off volume discounts
- **Enable Package Pricing**: Turn on/off fixed-price packages
- **Display Pricing Table**: Show/hide pricing tables on product pages
- **Display Position**: Choose where to show pricing tables

### Product Settings

When editing a product, scroll to the **Product data** panel:

1. Click on the **General** tab
2. Scroll down to find **Tier Pricing** and **Package Pricing** sections

#### Adding Tier Pricing

1. Click "Add Tier" button
2. Set minimum quantity (e.g., 10)
3. Set price per unit (e.g., 9.99)
4. Add more tiers as needed
5. Tiers are automatically sorted by quantity

**Example:**
- 1-9 items: $12.00 each (regular price)
- 10-24 items: $10.00 each (tier 1)
- 25-49 items: $8.50 each (tier 2)
- 50+ items: $7.00 each (tier 3)

#### Adding Package Pricing

1. Click "Add Package" button
2. Set exact quantity (e.g., 10)
3. Set fixed price for that quantity (e.g., 99.99)
4. Optionally add a custom label (e.g., "Starter Pack")
5. Add more packages as needed

**Example:**
- Package 1: 10 pieces for $95 (labeled "Small Bundle")
- Package 2: 25 pieces for $200 (labeled "Value Pack")
- Package 3: 50 pieces for $350 (labeled "Business Pack")

## How It Works

### Price Calculation Priority

1. **Package Price** (highest priority): If the exact quantity matches a package, the package price applies
2. **Tier Price**: If no package match, the highest applicable tier price is used
3. **Regular Price**: If no tier or package applies, the regular product price is used

### Frontend Display

- Pricing tables show all available tiers and packages
- Current tier/package is highlighted based on selected quantity
- Prices update dynamically when quantity changes
- Package buttons allow one-click quantity selection

### Cart Behavior

- Correct prices are applied in the cart
- Cart shows whether tier or package pricing is applied
- Subtotals are calculated correctly
- Compatible with WooCommerce checkout process
