I tended to let a lot of produce go bad until I did two things...
1) I tossed the crisper drawers from my fridge. Now all my veg sits out in the open staring at me when I open the door.
2) I finally used the "green bags" my Mom bought me ages ago. I was skeptical about an "as seen on" item, but they really do keep my greens longer.
Incidents of slime are much more rare now, saving me lots of cash.
