Some sites would tell you that sharing is its own reward. But at Perkopolis, sharing lets you get your deal for free.
Once you purchase a deal from Perkopolis, you will receive a referral link to share with your friends. Email, Facebook, or tweet your link to your friends and family. If three people use your link and purchase the same deal within 30 days, your deal will be absolutely free!
Finally, social media finds itself useful.
