Signing up for an offer..

Ok so I'm a newbie (not to mention a huge skeptic) to this thing and I was wondering if you could help me out. This regards www.freephotoipod.com >

1) If for example I sign up for the Blockbuster offer, do my 10 referrals also have to do this specific Blockbuster offer for me to get credit, or can they do something else like those diet pills or the credit card offer as long as they complete it for me to get credit?

2) I'm not really comfortable giving out my credit card number but I'm contemplating doing either the BLOCKBUSTER or VIDEOPROFESSOR. I'm leaning toward VideoProfessor because it's instant credit but is there any catch to the thing? I know I'll have to pay like $6.95 shipping but have any of you guys who signed up for VideoProfessor get screwed and had to pay up $69.95 for the CDs? Which would you suggest (Ancestry.com and InFone aren't available.)

Oh yeah, and if you live in Jersey how long did it take you to get your Ipod?

Thanks and I'd appreciate your advice..

theres a lot of information about the offers at www.ratetheoffers.com

cheers.
