They have increased their HP ink plan prices yet again. I went to cancel my subscription but was informed that the instant ink cartridges currently in my printer will stop working at the end of the billing cycle - in 4 days. My monthly subscription, regardless of usage, has paid for those cartridges. Since they are quite full I will wait to empty them then cancel my subscription. It’s a con since I have rarely used the number of pages I pay for a month.
