I found a site like this one earlier in the week, but didn’t manage to get the post in place.  I like the idea of planned purchases through the year, and feel that I could adjust the list  to my preferences.  Also, there is a needed place to put the stuff.  For such a need, I have in-laws to copy.  They have a closet set on each side with 1×4’s and vertical 1×2’s to support the fronts.  The boards have enough space to place cans.  I have already installed this idea in our pantry from the present shelves to the door frame, and have found the space useful.  I just need to figure out where the rest of the year’s supply should go.  But this does provide a plan once the location is determined.
