You can purchase cartridges direct from the manufacturer, Joann's, Michaels or SVGls. If you buy from a seller or individual make sure none are "linked" to a Gypsy or to their account because that is the only way you would not be able to use them. If you buy a cartridge, there is a place on the machine to link these to your internet account. I have over 60 cartridges and never use Cricut's monthly access because of all of mine as well as the free ones they offer. The internet site is Cricut Design Space and you can take a tour without having an account. See if you like it. I did!! Am very pleased with my purchase!!
