Lets do the math. i'll assume that both remotes have motion plus and wrist straps for the sake of the math and that they're actual Nintendo remotes. if any of this is incorrect then the value is less.
$199 - black bundle with Sports, Sports Resort, 1 nunchuck, 1 remote w/motion plus & wrist strap
$ 19 - 1 nunchuck
$ 39 - 1 remote w/motion plus & wrist strap
$ 29 - dual remote power station
=======
$286
This doesn't include the workout kit because I don't know what that is (if it's Wii Fit then this is an AMAZING deal and could you please share the site where you found it?). you can definitely get dual remote power stations cheaper than this, as low as $10. Basically, I don't think this is going to be any better than getting everything separately and separately you can pick and choose the actual items you want.
Thanks for the breakdown, I don't know the prices of each item...it's definitely not the Wii Fit, it's more like a fanny pack that holds the remote and stuff from what I understand.
