"Sell-by" ≠ "Bad By"

Eggs are commonly tossed after the "sell-by" date on the side of their package.  This doesn't need to be the case, as they are safe to eat up between 3-5 weeks after their sell by date if kept in the fridge.  Want to freeze them? (Yes eggs actually freeze - more here). Eggs can last up to a year in the freezer! 

Trashing one egg wastes 53 gallons of water! (source) That's like filling you bathtub to the brim, and then emptying it for no reason - plus you lose an egg!
