I had a previous bad experience with ordering a bundled 2 pack toner cartridges from a vendor selling through Amazon.com. The first set sent were not recognized by the SAMSUNG SCX3405FW all-in-one printer. After swapping for a replacement pack, only one of the two cartridges in fact worked, and the initial 50 printed pages or so were smeared and dirty. I lost faith in the so called compatible cartridges and went back to paying for the much more expensive SAMSUNG genuine cartridge I had to buy from Office Depot. The single SAMSUNG cartridge from Office Depot was priced at close to $90 on last check, so I decided to give INKTONER a try. I had to admit that I was rather apprehensive about blowing another $54 for trying another two "compatibles" that might again be a total waste of money. When I got my two packs, I carefully opened both of them, inserted each into my printer, and ran off a few test pages of WORD document and a back-white photo. I was pleasantly surprised to find that both cartridges worked, and the pages came out clean and sharp. I wrestled for a while when I was placing the order whether to just get one, or two. For order over $50, shipping is free, while I would have to pay about $32 (cartridge plus shipping) for one. I finally decided to take a chance and I was happy I did. The only slight disappointment regarding the ordering experience was that when the order was placed and accepted, I received an email confirmation ( with order #) indicating that once the order is shipped, I will receive another email notification with a shipment tracking ID for tracking the shipment. I checked my junk mail folder (and INBOX) and never did locate an email with shipment tracking information. After a bit over a week, I emailed INKTONER support inquiring about the status of my order. I got an email reply on the following day indicating that the order had already been shipped. I received the shipment on the next day. Not sure why I never received the shipment tracking information email. Maybe a glitch in the system or order process.
