Tip No 89 - Should I buy refillable cartridge?

Refillable cartridge seems like an excellent idea to slash printing costs, but it depends on how much you print. Remember, when you buy your refill ink in bulk, they have to be used up within 6 months. If you only print 1 page a month, normal cartridges is definately a cheaper option for you. If you go through at least 3 sets of cartridges every 6 month, that's when you can enjoy the cost savings of refillable cartridges.
