Do your research before you choose a platform to make sure you pick the one that's right for you. Be sure to check the fine print when you're donating through an electronic platform, because there can be hidden fees. Generally, if you donate to an organization through its official website, around two to three percent of that donation goes to things like credit card processing fees. Some external donation sites have even higher fees that can reach upwards of ten percent, although others like Facebook and the PayPal Giving Fund waive all fees for donations to charities, so it's important to do your research.
