I purchased my "file drawers on rollers" from a local discount store for under $50. It did require a little assembly.
Using print labels, I wrote the topic or subject on the label and attached it to the front of the drawer, like you see in the photo. When I have "stuff" on that particular topic that I'd like to keep for later, I simply slide it into the drawer. I really like this for storing all the little notes I seem to write while out and about - it allows me to easily and safely store them in a location where I will be able to retrieve them at a later date.
I also enjoy that the drawers pull out completely. I can plop it on my lap and go through it while watching TV or take it with me if I want all the info with me at a meeting on that particular subject or topic.
It has given me peace of mind because I can locate the information I know I "put somewhere"... It saves so much time and frustration!
I hope this simple tip will help you as much as it's helped me!
