I love
MyHabit.com (a daily deal, and exclusive shopping site powered by Amazon), I have personally bought several things from the site and have been super pleased with the service and quality. Right now for every 5 friends that you refer to
MyHabit.com you will receive a $25 credit....and you can refer up to 10 friends earning a $50 credit. This deal is only good through 12/13 so head over to
MyHabit.com and grab your own referral link so you can score you free credit. The BEST part is that your friends don't have to purchase anything, they just have to sign up and you will earn your credit.
