I have to say that I love getting rotisserie chicken particularly from Costco - from Megan McArdle (Bloomberg):
The rotisserie chickens were actually cheaper than buying and roasting my own. [...]
Grocery stores make them out of unsold chicken that is about to pass its expiration date. It’s an elegant way to make a profit out of food that would otherwise be a net loss. And it’s not just chicken -- according to Vasko, the ever-expanding prepared-foods section of the supermarket uses up all sorts of unsold produce and meat. It is, as she says, a bit like hunter-gatherers using every inch of the animal.
This is the sort of thing that no one talks about when they talk about innovation --and yet, it’s a major way in which our economy has become more efficient over the last few decades. Reducing spoilage means grocery stores can sell us raw chickens at lower prices -- and that we can get fresh, delicious prepared food at even lower prices. It’s a win for the grocer and the consumer.
