It really is staggering that a business that does $230 billion top line, 70% of the profits can come from the $4 billion of revenue they generate from memberships. That tells you how razor thin the margins are on their retail business, almost to the point where you're like, why do they care about growing sales at all? All they should care about is increasing retention of members.
