Kroger sells some produce in red bags for $0.99 if it's about to go bad. I have collected numerous of these bags and reuse them to buy avocados, garlic and even cheese for incredibly discounted rates!

Here are their other chains: smith's, king soopers, Ralph's, fredmeyer, food4less, baker's, city Market, Owen's, Jay c, QFC, gerbes, pay less super market.

I've done this for about five years with no problems.
