Bob,  I find what you are doing to be painful.  I tried to do it a
number of years ago.
As I remember there was one item that I looked at and said.
"Ah, haven't needed that for 15 years." So I chucked it.
Two days later I had to go buy one for $15.00 or so.

I hope that you put all of your fresh shelf space to good use.  :-)
