The Cluttered Fridge

I am unsure if it is our refrigerator - it is pretty average- or us, but we have too many condiments to fit on the door.

The freezer, too, is a cluttered mess, with nothing seeming to have a proper home. (Where do people put bags of frozen fruit or veggies? They are squished up on one shelf and fall out whenever the door is opened.)

I wasted money on plastic fridge organizers that did not work at all. What are some tips & tricks that have worked for you?
