How Quantity Rules Work
Minimum quantity
The minimum quantity controls the first valid quantity a customer can purchase.
Maximum quantity
The maximum quantity limits how many units of the product or variation may be purchased at once.
Quantity step
The step determines the valid increments after the minimum value.
Example
With Min 5, Max 50 and Step 5, valid quantities are:
5, 10, 15, 20, 25, 30, 35, 40, 45, 50
The quantity field begins from the effective minimum. Deviking MinMaxStep does not use a separate default quantity setting.
Blank values
A blank field means that the plugin should inherit the next available rule according to the priority chain. If no Deviking rule exists, WooCommerce keeps its normal behavior for that field.
