ProductBoxes – Mix & Match Box Builder for WooCommerce is a free WooCommerce box builder that lets customers build their own box, mix and match products, create custom gift boxes and buy product bundles. Shoppers choose eligible products, fill box slots, see live pricing and discount progress, and add their completed box to the cart. Create gift hampers, clothing bundles, snack boxes, beauty kits, samplers, or “pick any 3” offers without coding.

Set up a mix and match campaign in the visual editor, choose products and bundle discount rules, and publish with a Gutenberg block or shortcode. ProductBoxes calculates and validates prices on the server. 100% free: no paid version, locked features or account required.

Three ways to build WooCommerce product bundles

Tiered discount box builder: Offer bigger savings as shoppers add more items (for example, 10% off 3, 15% off 5 and 25% off 12). Show progress toward the next tier.
Fixed-size gift box builder: Let customers choose a box size, such as 3, 6 or 12 items, with a price or discount for each size.
Fixed-price mix and match bundles: Sell an exact number of eligible products for one bundle price, such as “pick any 3 shirts for $120”.

Requirements

WordPress 6.6 or later
WooCommerce 9.0 or later
PHP 7.4 or later

External services

This plugin does not connect to any external service. It makes no requests to other servers and uses no CDN, remote fonts, telemetry, or licence or update checks. All scripts, styles and fonts are included in the plugin.

Privacy

Optional builder analytics are stored only in this site’s database. They record builder views, product picks, tier milestones, cart additions and box purchases.

A random session ID is kept in the browser’s sessionStorage. No tracking cookie is set.
Only a daily salted hash of that ID is stored. No IP address or user agent is recorded, and the salt changes every day, so sessions cannot be linked across days.
The analytics setting and the mmbb_track_events filter stop all collection, including new purchases. Refund and cancellation corrections still apply when tracking is off.
Raw events are deleted after the retention period (90 days by default). Daily totals and order-line sales records are kept for reports and late refunds.

Gift messages are stored with WooCommerce order items. The WordPress personal data tools export them, and erase them when WooCommerce’s order data removal setting allows it.

Source code and build

The JavaScript and CSS source is included in the src/ folder, with the build configuration in package.json and webpack.config.js. React and the @wordpress packages are supplied by WordPress and are not bundled.

To build with Node.js 20.19 or later:

npm install
npm run build

The build writes production files to build/. Composer is used only for development tools (coding standards and PHPUnit) and is not needed to run the plugin.
