There are surveys under "earn daily"
you can do one every 24 hours.
I personally do my shopping through SR. When I need something big from
walmart (big price wise), I order online, through SR, and do site to store pickup. The price is the same, free shipping, and I get money. I also buy shoes from payless for my boys through SR. It's easy to spend $50 to get the free shipping. I also buy my household products through drugstore.com (through SR). They offer free shipping, and usually have an incentive.. x amount off if spending x amount. I also do any ebay shopping through them. Essentially, if it doesn't cost more money to shop through them, and I was already going to buy it, I do it.
Then, I go to the offers, and selected "most popular". I don't do anything that requires a phone number, because they WILL call you. I do have a second email address for all of the offers. You do often have to go and check that email, and respond to it, to get your money.
Doing these things.. I've earned $45 in a couple months for
disneyland. Last summer I put more effort into it (and started sooner) and I got around $100, and made super member. There are people that put much more time in it that me, and they earn much more. I am far from an expert.
I just need to remember to work on it all year long, not just right before vacation.
Good luck!
