I'm going to use our HP790C3B kit as an example. This kit is used for refilling the very popular HP 51645A black and HP C6578 color cartridges.
Here is the formula:
S = (RC x CCC) + (RB x CCB) - RK
S = Your actual savings over the life of the refill kit
RC = The number of color refills in the kit
CCC = Cost of a new color cartridge
RB = The number of black refills in the kit
CCB = Cost of a new black cartridge
Lets plug in some numbers.
Today I checked the prices of the aforementioned OEM cartridges on Staples web site.
HP 51645A - $29.99
HP C6578AN - $54.99
Our HP790C3B kit refills:
Black - 3 times
Color - 5 times
The kit sells for $27.95.
Here is the formula with the numbers plugged in:
S = (5 x 54.99) + (3 x 29.99) - 27.95
S = (274.95) + (89.97) - 27.95
S = 364.92 - 27.95
S = 336.97
Quite an eye opener isn't it? By spending $27.95 you can save $336.97. I would get some ink on my hands to save $337.00!
I believe wholeheartedly that if more people knew how much money they can save there would be a lot less of these cartridges ending up in the landfills.
Just please remember
, start small. If you've never refilled before don't start by ordering a gallon of ink.
