This may sound silly but it is something I started doing while I was bartending. I had wanted to save all of my tip money for WDW but I kept slipping. So I decided that every time I get a dollar bill that has one of my initials or my husbands on it inside the federal reserve circle it gets put in a tin. No mater what. I was amazed at how fast the money piled up! We also save all of our change.
