How to Enable BOGO Deals in WordPress

What Is the Enable BOGO Deals feature?

The Enable BOGO Deals feature adds the ability to create Buy One Get One (BOGO) promotions. Common BOGO patterns supported:

• Buy 1 Get 1 Free: Customer adds 2 items, the second is free
• Buy 2 Get 1 at 50% Off: Customer adds 3 items, the cheapest is half off
• Buy from Category A, Get from Category B: Cross-category promotions (e.g., buy shoes, get socks free)
• Quantity scaling: Buy 2 get 1, buy 4 get 2 (scaling discount)

The BOGO is configured per coupon in the coupon data, with the “Enabled BOGO Deals” master toggle as a prerequisite.

Why You Need It

BOGO promotions are a classic e-commerce tool for increasing average order value:

• Encourages larger orders: Customers add more items to get the deal
• Clears inventory: BOGO on slow-moving items moves stock
• Increases perceived value: Customers feel they’re getting a deal
• Simple to communicate: “Buy 2 Get 1 Free” is clear and compelling

For most stores, BOGO is a high-ROI promotional tool.

How to Enable BOGO Deals in WordPress

Click into the Classic Monks plugin settings in your WordPress dashboard.

Step 2: Go to the WooCommerce Tab

• Show Cart Messages: Display informational messages in the cart about active BOGO deals

Step 5: Configure Individual BOGO Coupons

For each BOGO coupon, configure the BOGO settings in the coupon data:

• The products the BOGO applies to
• The discount amount (100% for free, 50% for half off, etc.)
• The quantity thresholds (buy 1, get 1 free / buy 2, get 1 free / etc.)

Step 6: Save Changes

Advanced Options (Developers)

This feature registers 4 WordPress hooks in bogo-deals.php:

Actions:

• woocommerce_cart_loaded_from_session calls cm_validate_bogo_coupons() (Validates BOGO coupons on cart load (priority 20))
• woocommerce_before_single_product_summary calls cm_display_bogo_product_badge() (Displays BOGO badge on product page (priority 15))

Filters:

• woocommerce_coupon_discount_types calls cm_add_bogo_discount_type() (Registers BOGO discount type)
• woocommerce_coupon_get_discount_amount calls cm_bogo_coupon_discount_amount() (Calculates BOGO discount amount (priority 10))

// Hooked in bogo-deals.php
add_filter( 'woocommerce_coupon_discount_types', 'cm_add_bogo_discount_type' );

The feature modifies WooCommerce behavior by registering or removing hooks. Disabling it reverses those changes.

Troubleshooting

The BOGO is not being applied

Cause: The toggle is off, the coupon’s BOGO is not configured, or the cart does not meet the BOGO conditions.
Fix: Verify the toggle is on. Edit the coupon and verify the BOGO settings are configured. Verify the cart has the required products and quantity.

The BOGO discount is wrong

Cause: The discount amount is misconfigured.
Fix: Edit the coupon and verify the discount amount. For “Buy 1 Get 1 Free”, set the discount to 100%. For “Buy 2 Get 1 at 50% Off”, set the discount to 50%.

The customer is getting the BOGO on the wrong products

Cause: The BOGO product selection is misconfigured.
Fix: Edit the coupon and verify which products are eligible for the BOGO. The “Allow Same Product BOGO” option must be enabled for same-product BOGO to work.

The cart messages are showing but the BOGO isn’t applying

Cause: The cart messages are showing but the BOGO calculation is failing.
Fix: Verify the BOGO conditions (quantity, products). Check the browser console for JavaScript errors. Disable other cart-related plugins to find the conflict.
