You would have to create one limit for each product with a quantity value of 1, the period set to "forever" and the product selected in the "products" setting, and the order statuses you wish to take into account for the limitation.

Thanks and Regards")* is there a way, that a customer could buy only once but still pick what ever quantity he need that one time? kinda like a limitation not on the quantity entered but on the product selection instead?
