Costco expands hours for key member service
The warehouse club is always looking for ways to better serve members.

Costco offers a weird mix of consistency and surprise.
Members know exactly what they will get in certain areas. The company always stocks the basics when it comes to groceries, household goods, and other basics.

That experience never changes. You know you can buy the core grocery ingredients you need at home, but the other items each warehouse club stocks change regularly.
This changing inventory creates the "treasure hunt" aspect of Costco (COST) that keeps people coming back. You may go in looking to buy chicken, a toothbrush, and toilet paper, then leave with a canoe, a winter coat, and who knows what else.
For members, it's an exciting mix of intrigue and predictability.
