How to offer buy one get one free deals in WooCommerce

Decide exactly what the customer must buy and what they receive. A simple offer might be buy one red mug, get one red mug free. A more complex offer might allow any product from one category to qualify and give away a particular product.

Also decide whether the offer repeats. For example, should buying four qualifying items produce two free items, or should each customer receive only one free item? Write this down before configuring the rule.

For one fixed same-product promotion, create a separate two-item bundle or multipack product and price it at the cost of one item. This avoids discount calculations and gives customers one product to add to the cart.

This approach is limited. Stock may need separate management, it does not handle different qualifying and free products well, and it cannot automatically select free items from a category. For those cases, use an automatic BOGO extension instead.

WooCommerce core supports percentage, fixed-cart and fixed-product coupons. To make a customer-added item free, enable coupons at WooCommerce > Settings > General, then create a coupon under Marketing > Coupons with a 100 percent discount restricted to the intended free product. Customers must add both the paid and free items themselves.

Do not treat this as a true BOGO rule. Core coupon restrictions can limit products and categories, but they do not reliably express “buy product A, then discount product B” or add product B automatically. A shopper may be able to apply the coupon to the free product without buying the qualifying item, so only use this workaround with additional controls and careful testing.

For a proper promotion, install an extension that supports conditional free products or BOGO rules. In WordPress, go to Plugins > Add New > Upload Plugin, upload the extension ZIP file, select Install Now, and activate it.

The practical route is to use WooCommerce Buy One Get One Free when you need offers based on specific products or categories without asking customers to enter a coupon code. It is designed to apply the free-product offer as the qualifying item is added to the cart.

Open the extension’s promotion settings and choose the qualifying product or category. Select the free product, set the qualifying and reward quantities, and choose whether the reward is completely free or receives a partial discount. If the extension offers scheduling or usage limits, set those before publishing.

Check how the rule handles repeated quantities, variations, sale items and multiple qualifying products. Different BOGO tools use different matching logic, so confirm that the rule matches your wording rather than assuming that “buy one, get one” always means one reward per pair.

Place test orders for one qualifying item, two qualifying items, a qualifying item without the reward, and an unrelated item. Confirm that the free line appears only when it should, the discount is visible in the cart and checkout, and stock is reduced correctly for both products.

Check shipping and tax as well. WooCommerce coupons apply to cart items and do not change shipping by themselves, so a free product can still affect shipping or tax depending on your store configuration. Also test coupon stacking, logged-out customers, mobile checkout and cached cart pages before advertising the deal.
