I bought one toner cartridge and they inundated me with spam. I continued to get spam even after I went through the remove myself from the mailing list process.
I purchased the three colour toner cartridges as my yellow was getting low and i figured I would make one purchase do. The on line purche was intuative and had no unneeded extra steps. The shipment arrive well before the estimate and was in good condition. The only thing that could be improved would be if they accepted my Visa/Debit card.
Seems to last forever! It pays to spend more on brand names sometimes, although I didn't actually pay more because the online agent helped me bundle my purchase. Love the free shipping and it arrived in less than 48 hours from time of order.
