The suppliers on the internet can sell most products at prices that are well below the normal shop prices. Its quite amazing and one wonders sometimes if the quality is good. Online sellers do not have brick and mortar overheads to support and therefor can sell at a lower price and still make a living. Most consumers will sit up and take notice when they see the bargains that can be had from these online stores. They do not have all those high operating costs so they can lower prices and still make a good living. Being able to allow your children and family to print out pages without supervision is such a blessing. if the cost of printing is low then you really do not have to restrict the use of the printer.
