I am obligated by my work to offer this to customers when they buy an HP printer and I make it really clear that it’s a bad deal for most customers. There are some edge case examples, like a lady with a small business who always prints exactly like 3 pages a day. The other customers who agree to buy it are almost always the super old people who don’t want to have to come to the store to get more ink. I think it’s a shit program that should be scrapped entirely, but some people really don’t care if it’s a bad deal as long as they get the convenience. No different than 7-11 up charging shit because it’s easier to buy it at the market down the street than the Walmart a few miles down the road.
