    Thank you for your excellent service. I ordered ink cartridges for my OLD printer. I have been wary of "compatible" cartridges, as those I ordered from another online store did not fit my printer - though the order said they were compatible. But it is getting increasingly difficult to find cartridges for this printer. Castleink provided the correct cartridges at a very reasonable price and they arrived in just a few days - without premium shipping costs. I'll definitely be ordering from you again.

    Dear Bill,
    Being a middle aged woman, I'm skeptical ordering over the internet. I priced ink at the local stores and your prices were so low, I just had to try your site. I'm am so impressed with the quality and speed with which I received my order. I am forwarding your site to all my computer friends. It's nice to save time and money these days.

    Dear Sir or Madam,
    Just a note to thank you for being there, and saving me money on ink. The cartridges I received from you are working just fine. Thank you again.

    Just a note to thank you. I was very pleased with the quality of your ink cartridges, and the low cost too.

    I bought ink cartridges on your site. Your product was much better than other ink cartridges that I've used in the past. I was also happy with the price -- it was much less than what i have paid.

    I have two different printers that I am constantly having to refill because I print a lot. The problem that I was running into is because I print so much, it was just so expensive to have to buy refills for both printers' inkjet cartridges for the Epson and then, of course, laser toner for the Brother. Castle Ink's shipping is fast, customer service is excellent, and the product that they sell is superb. I have not had one single problem from any of the refills I have gotten from Castle Ink.

    Great web site! It was easy to find the cartridges I needed. Completing the transaction was a breeze. My shipment came on time and was well packaged. Keep up the good work!
