Donation links are nice because you can buy them super cheap and get a lot of authority out of them depending on which page they are on. I always browse Google for crowdfunding sites that are offering a link on their site in exchange for a small fee, usually $5-10$ for a PR3, PR4 or even a PR5. Finding places to buy donation links is super easy. Google these phrases: gofundme.com “link to your website” indiegogo.com “link to your website” kickstarter.com “link to your website” Here's a couple great examples of charities that currently offer good links on their pages. http://www.gofundme.com/shinethelight http://www.indiegogo.com/projects/digital-classrooms-online-video http://www.indiegogo.com/projects/hatchedit-com-free-community-calendar-the-power-of-crowdsourcing-local-events http://www.gofundme.com/chrisvoss Hope this helps you guys!
