HP, Lexmark, Dell Compatible Cartridges Needed.

Hi, I need a good lowcost supplier for compatible inkjet cartridges. I need Dell, HP, Lexmark, Brother & I may need Epson or Canon if demand comes for them. Most needed are the Dell, Lexmark, & HP. If you can not provide them at low cost, please do not waste your time or mine. I am selling below retail, so that gives you an idea of where we want to be price wise. I am refilling cartridges now, but would like to have some on the shelf for folks to purchase that are short on time. If you can supply what I need at the right price let me know. I may not start there, but I will grow to be a fairly large customer.
