I have always Loved Hp Products But here lately I had been Buying Hp Ink cartridges 20/21 for my 4315 multi printer from Office depot, and this is the third and last time I buy these inks cause I only have been getting on an average of 30 full pages of Ink from these cartridges not 250 pages as they suggest why is Hp shorting the Consumers, I know you have hundreds of complaints and mine might seem little but it's not little when Im Unemployed and living on a Budget that my money is taking away by cheating me on my ink.and WHY have you let this happened.it's time to fix this problem.Thank you for listening.
