Welcome to the Rewards Board!
There is a thread at the top of the previous page that will give you the run down on all the programs and how to get started.
MyPoints is easy, Creations Rewards is a slow earner (if you don't shop), Millers Reward Shop can be time consuming, Milesource is okay, LuckyPoints add up pretty quick and it's not very time consuming, Memolink is okay.
I do all of these and do okay. My favorite is Creations Rewards. When I shop online, I shop through CR. They credit quick and I have never had a single problem.
Good luck!
