Basically a very low risk bonds only account that still gets a better return than your standard savings account. I still keep enough in my regular savings so that I can quickly access it if needed.

Also I still have a 401k thats from a job I left 4 years ago. I definitely need to do that. Some day.

I use an app called Digit that constantly takes little bits of money out of your checking account. It varies the amount so that you never even notice it and I end up saving quite a bit with it. I use it as my travel/vacation fund.
