There are inexpensive binders. The cardboard in the binder is thinner and not as durable but they are good for single use or light use. I like that I can purchase a dozen and they are lightweight when they are shipped.
I purchased these view binders to organize a lot of material that I need for reference now and then. I would not get them for something you would use daily but for keeping a bunch of papers in order for an inexpensive price I consider a good deal.
