I called the number back and it was Direct Buy.  In order to get the Android tablet and $100 dining card I would have to go and sit through an one hour presentation and hard sell to become a member.  Even though they say no obligation, they're a hard sell and I can think of other ways to spend the $3,000 - $4,000 fee.

I got one too but I'm hesitant to call only to find out I've got to go look at timeshares or something equally uninteresting.

A promotional department would like a return call for me to be rewarded a new android tablet. Is this a legit company?
