Quantity Rules & MOQ

Minimum, maximum and pack-size rules for any Shopify store — enforced when the item is added to the cart and again at checkout.

• Rules where they belong. Set a minimum, a maximum or “sold in packs of 6” on a variant, a product, a whole collection, or for customers with a given tag.
• Enforced, not suggested. A Cart & Checkout Validation Function blocks an invalid quantity even when the storefront script never ran.
• Quietly corrected. The quantity selector moves to the nearest valid amount as the buyer types, and says why.
