I love Costco. I probably buy 90% of my household goods, electronics, and food from Costco.
I even have some meals here. You can't beat a Polish Sausage and Drink for $1.50 ... plus they have Churros, Pizzas, Chicken Bakes, Kal-Bi Bakes, and great ice cream.
Each Costco sells different goods and it's usually based on the economy average of the surrounding community. They don't have the nicest high end goods like the Irvine Costco, but they still carry some good items that other low income Costcos have.
However, this Costco is by and far the most crowded and insane Costco I've ever been to. Definitely avoid this place on the weekends, but even on a weekeday you'll spend 10-15 minutes in the checkout line waiting for your turn.
Love Costco... but hate the lines. They need to open another branch.
