Sign up for a Groupon account, if you don’t have one already and then create your personalized referral link for the Real Simple $500 Groupon sweepstakes and get five friends to sign up. After doing so, you’ll receive a $10 Groupon credit which can be applied towards your account.
I’m not entire sure if this credit will be a code which comes by email or will be automatically added to your account. I’ll let you know if I find out.
Thanks, Swag Grabber!
