I wouldn't do it.

These types of promos have it all in with those other vendors.
Glad I was looking to buy some music recently otherwise I would have signed up for a bunch of cr*p, that I wouldn't want....

The company I went through was offering a new Sony Mini dv DVD camcorder, to test and also keep after completing the survey, and a few offers. Did the offers,got no camera,no survey.

It's ALL BUNK
