I have a subscription to the HP Instant Ink program. I had 6 months free when I bought a new printer. I did not think I would like it based on some of the reviews I read, however, it has turned out to be quite valuable. When my free subscription ran out, I subscribed to the 500-pages per month plan. I think it is around $18.99 per month. Under the 500-pages per month plan, I can roll over up to 1500 pages at any one time.
Full disclosure, I also use it to print stuff for my online store, which is why I have the 500-page plan. I think they offer a 300-page plan for around $12 per month and you can roll over up to 900 pages. There is even a 100-page plan for about $6 per month.
For any of the plans, If you reach your monthly page limit and have used all your rollover pages, you can buy extra pages at a rate of 10 pages for $1.00. I had to do that once when I reached the 700-page monthly limit when I had the free trial. Back then, I was printing EVERYTHING, including personal stuff like pictures. Typically, I print 350 to 400 pages a month, that's for mystery shopping, audits and my online business. Some months, especially at the end of a quarter, I may be closer to 500 pages. I could probably get by on the 300-page plan since I now have enough pages due to rollover, so I may downgrade my plan at the start of 2024. So, I'm easily able to print my fake surveys, shopper guidelines, and even the massive green/white fuel station audit guidelines. Although I upload the digital files of shopper guidelines to Google Drive so I can access them easily on my phone, I still prefer having a physical copies of stuff in the car as they are easier on my eyes to read.
Another benefit is I don't ever have to go out and buy ink, or worry about running out of ink. HP is very good about shipping cartridges automatically well before I need to change them out.
HP recently started a similar program for copy paper. I have not tried their program. Instead, I buy a box of paper at Sam's Club when they have it discounted. I've also gotten good deals buying Amazon Basic paper. For that, I specifically buy it from their returned stock because it is often heavily discounted and there is nothing wrong with it, other than someone returned it.
