These guys are always on top. I never have had a problem ordering supplies from them.


Very impressed. Ordered was shipped and received in time frame given. Was informed of tracking information so I could follow order. This was probably the easiest online order I have ever done.


Product delivered on time as promised. Quality appears to be very good. Great pricing!


Easy process to order. Confirmation and follow up with shipping date. Product arrived on time and exactly what I needed.


The toner works great and saved me a fortune! Quite happy with my purchase. I'd love it if there was an obvious and simple way to ship back my old cartridges in the same box to have them recycled...


"Easy & straight forward ordering process. Great search capability. We are using them as our alternative vendor for our Canon Image Runner toner vendor."


"I would recommend this company to other people without reservation."


"Return purchaser - product seems to work great so far. Hope second product performance goes as well as the first."


"Fantastic delivery received right in time. No games just great service."
