One other thing....

Your taste and preference may change. I bought a type of B&W paper in the amount of what I thought I would use in a year. My taste changed. My standard changed. My preference in subject evolved. They are still sitting in my refrigerator vacuum packed.

It's one thing to have $150 worth of paper in my frig. It's quite another to have $2000 worth of stuff in frig....

Yeah, you could sell them but you'll likely take a significant hit when you do.
