I love Costco for the savings but they need to build another warehouse, maybe in the Spring Mountain or Blue Diamond area. This store is always so crowded. Of course for some reason people have to stop in the middle of the aisles instead of to the side so getting around is frustrating. And parking is a nightmare. I just go straight to the parking spots by the gas station and make the hike to the store. It's quicker than trying to find a spot closer to the store.
That being said, I've always had great service here. The cashiers are friendly and fast and the Member Services people have always been pleasant. I'm there once a week and have never had any problems with the service. Just with other shoppers.
