We have a smal business but we go through tons of color ink and we were spending a bundle on ink cartridges, refillls, we tried it all. One of our clients has put together a resource site for printing supplies and services of all kinds. The information is unbiased and shows you just about everything out there. Whatever your print needs and demands are I would recommend checkingthis site out and seeing where you can save money. It's free and you don't have to sign up for anything, it is simple an informational site.
