Staples is okay if you really need something in the realm of office supplies and just happen to be near nothing else. Otherwise I would keep on driving.
There are no good deals at Staples. I have found myself in there a handful of times in dire need of something and have come to the terms that they are overpriced and dont really carry a great selection of things such as computer supplies and such.
On the subject of price.. I had received a $10 gift certificate to Staples for some odd reason and went in to use it.. By the time I bought my small bundle of school supply items I found that I was basically paying what I would have at any other "normal" store with competitive prices.
