So basically if my diapers are now only giving 5% since mom is long expired, all I need to do is add 4 more of these items, and my diapers become 15%?
Do I need to add them with every diaper shipment, or do I just set up that these should ship continuously the same months that my diapers ship?
Does amazon send you some confirmation letting you know that you now have 5 items and all your purchases will now be 15% instead of 5%?
