unorganized=tons of extra money spent

Has this ever happened to anyone? I went through my pantry and had double of a ton of things because either I was to lazy to look through everything and make sure I didn't have it before I went to the grocery store to get it or I couldn't see it because I was so unorganized.

Result I have two bottles of apple cider vinegar-sidenote does anyone know if you can use this past the expiration date?- Tons of half opened sacks of shredded coconut, nuts, anything you can think of. Yikes, while trying to cut back and save money on other things I just could have gone through my pantry and saved some on my grocery bill.
