There are many places you can buy laserjet toner cartridges, but I have found that not every place that sells laser jet toner cartridges sell good ones. I have bought some bad cartridges over time and I have learned to stick with the places that I know I can trust. One time a bought one when I opened the package the toner inside was no good for some reason and it was a hassle to get my money back. Another time I bought a remanufactured one and it messed up the printer. So I no longer buy remanufactured cartridges. I am not saying that these kinds of cartridges are bad, but I have had bad experiences with them. So I make sure that I check out all the information about the cartridges and the place that is selling them, I check their return policy and try to see if they have not complaints written about them.
