When I received the shipment, there were 2 cartriges missing from a total of 14 (?)cartriges. I called few days later and I got the 2 missing cartiges 2 or 3 days later. During the telephone conversation, she was very polite and no question was asked, she just said sorry and promised to send the missing items right away.I would buy other items from AMAZON online in the future. Because I know it's a reliable place to shop and I have built up my trust in that company (It was the first time I bought items from AMAZON).
