I live in another town from Staples so don't get into the store very often. Buying the 5 ream package is a winner for me as I use a lot of paper and now I won't run out before my next trip into town. Even though it mentions for black and white copies it works well with colour for my purposes which are for my personal and students' copies of knitting patterns.
I bought this paper primarily to replace very expensive Xerox paper that kept jamming up in the ancient Xerox copy machine... this stuff was meant to be utilitarian and it does what it needs to do...make copies that don't jam up the machine. I think the brand name paper was too thick...who knows...
