Here is a set of 14 inkjet cartridges that are comparable to the Brother LC41 series cartridges. Only one set is pictured, but you will get three complete sets (1 each of Black, Cyan, Magenta, and Yellow), and two extra yellow cartridges. These are surplus from a local office. There is no expiration date or manufacture date anywhere on the boxes, but they are all still sealed in the original plastic inside the box. I cannot guarantee that they are good, but I can guarantee that they are cheap! See below for the Brother printer models these should fit according to what is printed on the boxes.
These should fit the following Brother printer models: MFC 2106, 3240c, 3340cn, 420cn, 5440cn, 5840cn, 620cn, 820cw. They may also fit other models. If your printer uses Brother LC41 series cartridges, these should work.
