What is cheaper: Copy shop vs. buying Ink cartridge?

printing at Copymax ($1.29 per color page) or buying a color/b%26amp;W cartridge.|||I%26#039;ve often thought about it. If you%26#039;re talking about printing pictures on photo paper, I actually believe it%26#039;s cheaper to just go to Walgreens during a 19c per copy sale and have them print them up from your digital camera. Office Depot usually only charges me 10c per copy.. So when you factor in buying the printer and cartridge it%26#039;s probably cheaper to just have the copies done at the copy shops.|||buying a cartridge if you are paying 1.29 a sheet. Over here it is only 10 cents black and white and 20 cents color. you better check around.
