Cage-free eggs.

The little corner store where I do all my shopping has started to carry cartons of cage-free large eggs, $2.99 a dozen.

That's three times as expensive as the $.99 medium eggs I was used to getting, but treating chickens better like that is worth that to me.

And, actually, the eggs are noticeably larger.  It only takes three of them to make my omelette I always eat on Sunday, not four.
