Rated 3 out of 5 by Things worked out differently than expected I purchased this two pack of black ink printer cartridges not realizing that I was going to make the long trip into town to visit Walmart.......where I could have saved a slight amount on the purchase but overall from a price perspective the amount that you can obtain the cartridges from HP with free and fast shipping is really decent........and simply awesome if you dont happen to visit a Walmart that is about 45 miles away. I wish my HP printer wasnt so ink hungry though it is an older model now.....as for the free return envelope it saved me from tossing the cartridge into the burnable trash. I hope it goes to good use but I hope that HP doesnt simply reload the old ones to resell as new. August 11, 2014
Rated 5 out of 5 by Fast and perfect I received my order very fast. I am totally happy with my purchase. It is great to have an ink supply so easily delivered to my front door. I will order again. I would recommend this convenience to my friends and family June 16, 2014
Rated 5 out of 5 by The product is great. As previously stated, I am happy with the service, the speed that the product was delivered, the free shipping and handling, and the quality of the product. I am puzzled by the question mark appearing in my HP assistant AP? I do not understand what they want or are asking me to do? Please explain, because I have tried several times to see if I could satisfactorily answer them? Ms. King April 18, 2014

Rated 5 out of 5 by great ink product Great product. it works great in my printer. The price was really good and It came exactly when they said it would. I love HP products. April 4, 2014
Rated 5 out of 5 by Love HP & Your Ink Cartridges I went to print out an important document when I noticed that the ink signal on my printer was blinking. I needed the document in the mail by morning, so I went onto the HP website and ordered a 2-pack of the black cartridge. I not only got a reduced cost, but I was able to get FREE overnite shipping. How wonderful was that! And, the HP cartridges were delivered to the front of my door the next day. Amazing! I removed the old & plunked the new cartridge into the printer and I printed and mailed my document. Thank you HP. You are the best. January 18, 2014
