Office Max prices are shockingly too high, so I never shop there. Staples is as a much better deal.
In addition to only having 5 OMs for the entire Houston Area, we don't have Staples. That leaves the field to Office Depot.
If you're trying to save money, you need to shop carefully at any of these places. I've determined that they're fine for pens, pencils, paper and file folders (unless Costco carries it, in which case Costco is cheaper) but outrageously high on electronics, toner and software.
