Like everything else, it is wise not to have more than enough. But you never want to buy too much to the extent that you over extend the shelf life of the ink.

Some online and retail suppliers offer heavy discount schemes on their products to clear out their old stock and enhance sales. You will also get these products at wholesale prices if the volume of the purchase order is large. Organizations that frequently use their printers and also use varied kinds of printers can purchase printer ink in greater amount from these wholesalers. But, what about infrequent printer users! If you rarely use your printer for your home printing needs, it wouldn’t be wise to buy ink in large quantity and go too far with the shelf life of your printer ink.

However, storing ink is easier than storing a pile of cartridges. You can refill whenever your inkjet cartridges run out and this way you can extend your cartridge life by using ink refill till it is possible. Thus, storing ink in large volume will save you money on buying a replacement one. All you need to do is to purchase a refill kit for your printer type, like Epson Ink for Epson Printer or HP ink for HP Printer.

But before you buy, it is wise to compare prices online and always find out if what you are buying is compatible with the printer brand you own. In a nutshell, you should always buy ink as per your specific printing needs and requirements.
