How does the number of items ordered affect your recommendation?

Lydia and Jon order their holiday gifts through the mail. They have spent many evenings at home comparison-shopping through gift catalogues and have found all the things they need from three mail-order houses, B.B. Lean, Spoogle"s, and Sea"s End. The purchase price for their selections from each catalogue is given here. The shipping and handling charge per item is also given. If Lydia and Jon want to order all their gifts from the same source, which catalogue should they choose? How does the number of items ordered affect your recommendation?
