Amazon calculates the total shipping charge to the customer as follows: $4.00 + $0.50 x (25 lb. + 1 lb.) = $17.00. Item-based example: You set a per-shipment rate of $4.00 and per-item rate of $1.00. A buyer orders two products from you. Amazon calculates the total shipping charge to the buyer as follows: $4.00 + $1.00 x 2 items = $6.00.
