Quick, shameless referral plug here:
To save money for the future, I use Acorns. It rounds up spare change and regular investments and puts it into an investment savings account that you have full control over whenever you want. It's a really great way to save money without having to think about it and Acorns has saved me a bunch of times in a pinch.
Full disclosure: I get $5 for everyone I invite after their first deposit. Not only that though, for every account made, Acorns plants a REAL OAK TREE to help invest in our planet as well. So... maybe think about signing up? Use my link:
