I get all of my manilla envelopes, pens, packing tape and other supplies at Staples. They are also great for when you need copies made. Occassionally I will need to get 500 or 1,000 copies. The more you get made the cheaper the price is per item. I will leave the original with them and they will make my copies while I shop. I have found their prices on manilla envelopes better than you can get at Office Max.
