Teachers Pay Teachers
This is an open marketplace for educators to buy and sell teaching materials and products. Teachers can choose to sell digital downloads, various custom printables, and shipped hard goods such as board games and card games. If you're an educator and have created your own game, you should consider selling it on this marketplace. TGC participates in their referral program and they will pay us a 5% royalty on anything you sell on the site. This is an extra royalty from the company and doesn't reduce your amount.) http://www.teacherspayteachers.com
