John, Firstly, you can set a minimum bid of $0.02 for your keyword. So, if you set your bid at $0.02 and add 900% placement, you’ll get $0.18 for your single click. Furthermore, if you choose the “up and down only” bidding strategy, you may get higher spending starting at $0.18, depending on the Amazon auction; we can’t tell you the exact CPC.
