Comments about HP 645A (C9731A) Cyan LaserJet Toner Cartridge:
With Staples Rewards and the recycling program, the price gets reasonable. Though they don't stock this at the local Staples store, we can take the empties there for the recycling program. We have had many problems with refilled cartridges especially at inopertune times.
Bottom Line Yes, I would recommend this to a friend
