I have a HP Photosmart 3310 printer that just went Tango Uniform! I bought refillable cartridges and have refilled them several times and saved me probably hundreds of dollars. They are opaque so you can see when they are low and have a neat little plug that removes when you need to refill it. They worked great and still do. I got them from a great vendor at the local computer shows in my area, Lane from Atlas Business Systems in Reading PS (http://www.printerrefillkit.com/).

I have the whole set (6 cartridges)HP ink cartridge 02. I will give them to the first person that can use them. I just refilled them so they are all full but I don't know if they will last the shipment if they will dry out or not. I want to "pay it forward" so I will send them free to the first person who can use them.
