For years, I not-so-affectionately referred to printer ink as the "great money eater". It used to be. It would be $25 (on the cheap end) to buy a new printer cartridge. OUCH!
Now, thankfully, there are a myriad of ways to save money on printer ink. The easiest way to save money is to refill your cartridges. The regular price to do so at Walgreen's is $10 for black ink & $15 for color ink. However, they frequently run specials. To make it even better, you can use Walgreen's register rewards to pay for your ink. Talk about making the most of your money!
Unfortunately, our printer ink can't be refilled at Walgreen's. As a result, we go to Costco to get ours filled. We pay $7 for a black cartridge refill.
There are some people who are vehemently against refilling your cartridges. It will void any printer warranty if you do. Some claim that it ruins your printer. I have never personally had any problems using refills nor have I known anyone who has. If you just aren't comfortable refilling it, then you can still get credit at various office supply stores like Office Max for recycling your cartridges with them. The standard rate is $3 per cartridge that you bring in with a limit of 10/month for some stores.
The other HUGE way that I save on ink is by only printing in black. I rarely use my color ink. Then, I go a step further and print everything on draft quality and quick-print; both of which yield even more savings by preserving your ink.
What do you do to save money on ink?
