I needed printer paper and was near the Staples. The store has two prices: one for general customers and one for rewards members. I took advantage of the rewards price but only because I had a phone with a web connection at the time. Paper looks ok. Not especially good or bad.
I pass another office store that is closer to my home to shop at Staples. The staff always greets me pleasantly and interacts in a professional manner. That is worth the extra mile or so.
