What kind of demented toddler would even buy a printer attached to a subscription service? Printing is the definition of a thing that you do so sporadically and randomly it’s almost questionable to even get one. If you have some kind of cheap printing shop, school, or library super close by to you, then it’s not even a competition. The whole reason people buy printers and ink cartridges is so they can print something on demand at any time for essentially free (besides the odd time you might need another cartridge, which is even rarer to happen).
If someone buys a freaking “printer subscription month”, I guarantee, they’ll print one, MAYBE two papers, and not use the rest of it. Then repeat the cycle every time you need to print. $15 well spent, huh?
