Product Pack Sales for WooCommerce adds pack and bundle options to a normal simple or variable product. The customer chooses Single, Box ×4, or Pallet ×20. The cart quantity is the number of packs. Stock, weight, and availability use pieces: packs × multiplier.
Set packs on one product from the Inventory tab, or on each variation. One pack is enough. Names are yours; Box and Pallet are only examples.
This is not a multi-product bundle builder. It sells the same product in larger pack sizes (box, case, pallet) with correct piece-level stock.
All features included in this plugin work without payment, license keys, or upgrade.
Catalog-wide packs, product/category exclusions, a custom pack price, and packs-only mode are available in a separate Pro add-on. That code is not part of this plugin.
