Just a quick look at those kits, and they are definitely charging a significant premium.
The basic kit is $150, and you get a baofeng, cable and "manual." I don't know what instructional material they provide or its quality, but I know for sure there is tons of free high quality educational material online. Also there are free online practice test sites too, that have the actual test questions. You say you already have your Tech, so you can get on the air with that already.
Here is most of what comes in that basic kit if you just buy it yourself.
