Not Costco's - have been to many over the years and they have some of the best maintained, good quality carts you don't mind dragging across their gigantic parking lot.
Free college tuition for one. Defined retirement. Very decent health care (better than a well known Southern multinational you've heard about corporate care)
It's all gone now, I believe, now that the family list control of it (but I thought the employees owned half of it :S ?)
