Of all the Cartridge World outlets in the Tulsa/Broken Arrow area, the one at 6422 Elm is the best I've been to. I am a writer currently working on a new book. I go to Broken Arrow once a week for an author meeting. When I'm out of ink, I just stop by this unit with my empty cartridge and they always have a freshly loaded one available, making my visit short, quick, and efficient, and I never have to wait around. The folks at Cartridge World, Broken Arrow are always courteous, friendly, and most importantly, helpful. They know their business, and the cartridges I get there are perfect. They save me money, time, and aggravation. What more could anyone ask?Jim Laughterco-creator of Galactic Axia bookswww.galacticaxia.com
