We had some old ink cartridges that we didn’t need anymore. I hated to throw them out so I researched ink/toner buy-back sites ... I wasn’t sure if they would buy back ink cartridges so I messaged them and included a picture of what I had. I received a reply very quickly and was told that they would buy them back and they sent a prepaid label. I mailed the cartridges to them and they contacted me letting me know they received them and that they would be sending a check…which I just received today! Very pleased with this process and with the customer service provided! If we ever need this service again I will definitely contact them again!
