Thanks. I saw them. I guess I should have explained more. Every place I try to order has shipping costs that don't make sense. Usually if I buy in quantity I save on shipping cost per item. But when ordering bioxtra, all the places I've looked charge five dollars shipping for one tube, ten dollars shipping for two, etc. Usually shipping costs increase more slowly as the quantity goes up.
