How many ounces are these bottles?

Is there a shipping charge for a purchase over $100?

What is the Yield on one bottle of Ink

What is the estimated number of copies per bottle for color and black printing?

If I buy a new bottle of any of the Canon GI-26 inks--black or color--how long will they keep and still be good before opening? And after opening? If poured in the printer ink well, do they have to be used within a certain time to prevent printer issues?
