I ordered a set of cartridges. Took two weeks to find they did not have them, and did not know when they would get them. So I called them, and was informed they would take 2-3 weeks to get a refund. I would be very cautious dealing with this company. Meanwhile I had to just go ahead and buy my cartridges from Staples.
