If you haven't joined yet, you can earn points for doing things you already do. Searching the web, printing coupons, shopping online. There are even fun things to do like answering polls and searching for codes! You can earn points for many things. The main thing I earn points for is Amazon gift card! Nothing like free money!
So what are you sitting there waiting for?!?!? Get going and sign up now :) (p.s. you get bonus points for just signing up! and it doesn't take long for your points to add up!)
