Add-ons
Set products to be ordered in specific quantities by enabling the Product Multiple Order Quantities add-on on your Straightsell website.
This add-on will enable you to specify a number that will be used as a unit multiplier when adding a product to the cart. If for example you set a product order multiple of 5 the customer will be restricted to adding unit quantities of: 5, 10, 15 etc. to the cart. Once in the cart any alteration of quantities will be controlled to be in line with the specified order multiple.
This add-on also works together with the Product Minimum Order Quantities add-on to define valid product order quantities.
