Paper choices for Canon 9000 mk II
If you are a Costco member, or know someone who is, you can order the Kirkland Glossy Photo paper in 13" X 19" from their website. Not available in the store, but web only. It costs a little less than $1 per sheet before shipping. Have it and it works fine with my Pro9000 Mk II.
Edit: It comes in a 50 sheet pack
