Of course, voting for your candidate of choice is the best way to exercise support, but GiveMini is a convenient platform that helps politically engaged citizens to show support with another key factor: their wallets. The simple platform lets people donate small amounts to the progressive candidates in whom they believe, putting spare change toward national change (as GiveMini's slogan attests).
Though GiveMini is indeed focused on donations in amounts no greater than spare change, it collects all this change without any cash. Rather, users enter their credit cards into the app, and it monitors their expenses, rounding every purchase up to the nearest dollar and donating the difference. For example, if a user bought a coffee on their credit card for $2.50, the app would round that up to $3, donating the extra 50 cents to the user's pre-selected progressive candidate.
