I always check out this paper for their deals on cases. I use the rebate that's often offered to buy another case then use that rebate to buy another case and so on etc. The quality of paper is great no problems with it in several different printers at work and home. The rebate system that Staples has online is easy to use. The online instructions take you step by step. Just be sure to keep your receipt to do this online. Then you can check online on the status and they usually will send you an email to let you know when it's on its way.
I have been using this Staples brand copy paper for years and have absolutely no problems with its performance. It has not caused any jams in the equipment .
