Office Depot is certainly the catch all for your office and school supplies needs. They've got everything you could imagine for a small business start up or a teacher. From the furniture to the printers to the paper and the ink. Pens and markers galore. Post-It notes you never before imagined. Desk organization. Shipping supplies. Even computers, software and accessories.
All that aside I gotta say it's a bit overpriced. And their membership can hardly be considered any kind of benefit, affording you just 2% off purchases. There is at least a business center that can handle your many printing needs if you don't have the time or patience to do it yourself. But in the end nowadays you can do most of what they do online for cheaper at a place like VistaPrint. Also you can find plenty more stationery and pen selection elsewhere too. At the very least this is a good start in times of dire need.
