WP Share It Now

WP Share It Now is an easy-to-use, newbie-friendly plugin that will allow you to finally send viral traffic to your blogs, increase your sales, and it will even build a responsive list for you.

It works in a very easy way…To put it simply, you only have to incentivize your visitors with a free offer and they will “pay” you with a share in Google, Twitter or Google+. Also, you can add coupons or discounts!
