I make multiple copies during a work day. Mostly for my own use printing info off computer during business calls. Most get filed or thrown out. For this it is perfect as cost is low. I would use for a casual letter but not for something important such as a formal business letter. Only problem I have had is it jamming my printer by having more than one page pull through at a time. But this is not a constant but a random occurance. Rarely happens with more expensive paper.
I ordered paper from a different on-line company for years before they were acquired by Staples. The paper I bought from them was of better quality and was less expensive. I am self-employed and have to keep cost as my first consideration. Although Staples' brand of paper is okay it is a bit flimsier than the paper I received from the other company. It seems as if Staples' paper is affected more by the Florida humidity than the other brand.
