I have discovered that one file folder per one hanging file folder makes my files look perfectly organized. Appearance matters and when I open my file drawer and everything looks tidy I am more motivated to do more work. Simple technique simple and inexpensive office supply but completely invaluable. These hold up better than the supplies provided by my office so I actually will periodically buy my own to increase my organization. Others in my office have offered to pay me to organize for them--it's all about the tools!
Home office supplies (especially ink cartridges) are expensive. We buy "generic" brands often. In this case PENDAFLEX brand name was quite a bit more expensive. Staples brand more reasonably priced & served our purpose. Staples coupons should have a longer "life span." Often I don't use them because they have expired before I need the item.
