How to Organize a Tiny Pantry

I currently have to use the world's most inefficient pantry.  I don't like clutter and the older I get...the worse this gets for me.  I know it doesn't bode well for my future peace of mind but oh well.  What can I do?  *sigh*

The door is 18 inches wide.  

*BLINK*

There are only three shelves and the shelves aren't very deep.  

This is my problem.

 

 

12' wide and one piece.  The one I saw at Home Depot was two pieces attached with a c-hook so they've forever sway when you opened the door.

I just ordered this to hang on the door:  ClosetMaid Adjustable 8-Tier Wall and Door Rack, 12-Inch

And I ordered some more canisters and whatnot so I could stack stuff neatly.  I like these because they come with their own measuring cups and they are BPA free:  Sistema Klip It Bakery Container 

 I love the canisters that clip.  The solid clunk makes me know it's airtight!

I'm kicking myself because I just ordered some stuff from The Container Store and had I thought about this before then I could have added to that order since the Elfa sale is going on currently and, as always during the sale, all Elfa components are 30% off.  I could have added some things ya know?  Oh well.  I hate shipping fees more than anything and I haven't the slightest reason why.  Crazy huh?

Do you have a pantry this size?  Any tips on how to utilize it properly?  What do you do so it doesn't drive you insane being a cluttered disorganized mess?
