Starting April 2nd, there will be a new site available for finding daily deals for homeschoolers. Educents is right now gearing up for the launch of their website. If you visit now, you can sign up for a $15 gift card to use once the site is up and running.
While I've never personally ever shopped at Educents, getting $15 up front isn't a bad deal. If you don't use it, no sweat. I get the impression that this site will work very much like Groupon or Living Social coupon sites do (if you are at all familiar with those.) Discounts from 30%-90% are promised. If you do end up using Educents, be sure to come back and let us know how it went - your impressions, whether you got a good deal or not, would you recommend it, etc.
