Hi!
LuckyPoints is very easy. They usually have a site of the day, a trivia question and from time to time they have sites to visit. (Of course you can shop through them and they seem to have sign ups.) I can't tell you about how the shopping or signups work because I've never done them.
9,000 points gets you a $10 gift certificate.
11,000 points for $10 cash
7,000 points for 2 Hollywood video rentals
21,225 for $20 WebCertificate
5,000 for $5 Burger King
There are many other prizes, but that will give you an idea.
If you do this one, you might as well do SavingsRegisterRewards.com and PCHPoints.com as they are all basically the same.
I hope this helps!
Lori
