Costco Wholesale - Livermore

What Xuan C likes about Costco Wholesale:
I've had my Costco membership for 1 year now. I find myself going to their gas station often. Cheapest gas around! Also some great pizzas too! But duuude! Note to self, do not come here on a Sunday. It's a zoo! All I wanted was a slice of Pizza. The lines were super long. View all feedback.
