Is There A Market Anymore For Changing Ink In Printers At Local Businesses?

about 6 years ago, i got an offer to buy a business like this and it was doing well. But now with office depot and places filling cartridges (seems cheap) is there a place for this market anymore? I am not looking to get rich, by the way. Just a side gig.
Also with more and more people being more computer literate…?

Is There A Reason Why I Cannot Find Any Of The Beech-nut Brand Juices In My Local Market Anymore? ?
