Do you see a logo “STOP”? These products cannot be ordered at this time. They may only be ordered by an authorised purchaser and / or upon request to your purchasing department. Use on the product detail page the button ‘Recommend item’ to send the link of the product to the appropriate person in your organisation.
It is also possible to choose the option “Without optimisation”. This option is based on your original selection. That means you may choose items from a specific warehouse or items with a shorter delivery period.
