Quantity increment
A quantity increment is the step a buyer must follow when choosing a quantity, such as multiples of 6. It enforces case packs and bundles so orders match how stock is packed. A buyer can choose 6, 12 or 18, but not 7.
Example
With an increment of 6, the quantity selector moves 6, 12, 18 and so on.
