Kvod haRav, if someone is careful to use AmazonSmile or similar options that allocate a small percentage of their purchases and donate them to BeEzrat Hashem (hopefully) or another good organization, is this Tzedakah since it did not come from their own pocket? If it is not, since they made some effort, what mitzvah is it? Lastly, is the mitzvah of Tzedakah accomplished at the time when you intend to give it, when you actually set it aside, or when it enters into the hands of the receiver?
