I took a chance and bought ink cartridges online from 123Inkjets.com. The black and color package retails for $60 including tax. I got the Black for $15 and the color for $19 and used an online coupon code so I got an additional $7 off.
I received them in 3 days in a new, sealed package.
Online coupon site: CouponCabin.com. Just search for what item you are in the market for and it will pop up with a list of sites and how much discount you'll get.
This is like a whole new world to me.
