Ordering a full pizza? Call ahead @ (530) 406-2120 to place an order, do your shopping, then pick-up the pizza afterward at the food court. Cuts down the wait time!
When I walked in the woman at the front yelled at me to show her my Costco card as if she were the police. Terrible store, I wish there were a different one around here.
You can buy alcohol at Costco without a membership. CA law prohibits charging membership fees to purchase alcohol. If your checker doesn't know this, ask for their supervisor. Most of them do.
