I can't even find the DCF889 for sale at Home Depot (online or retail) and a lot of the tools are not on amazon.com. That factory outlet site seems to have a good selection of the 20V tools but the kits are just not useful to me.
It's very frustrating. I just spent an hour looking up the price of each tool or kit with various included batteries, bare tool, etc. and writing them all down and I haven't got any further. It seems my best choice is to just buy the DCD980L2 drill/driver with included 3x 3.0Ah batteries and then buy bare tools as you suggested.
It's basically $724.97 for the drill with 3 batteries, jig saw, circular saw, and the 300lbft impact driver. Doesn't compare too well to the 9-tool combo on the older 18V tools. Keep in mind there is no 20V cut out tool yet, too.
