with ship and print, you can get pretty close with the kitchen scales, add a little extra, if it is cheaper then go with flat rate............only drawback to click-n-ship, so far..............it will not let me bomb anonymously, hehe. So I have to eat that and pay a little more for peace of mind, and minimal house bombings.
But it will save you some money over the course of a year, that's another few cigars!
