I live in currently live in Anchorage. While the city population is ~250,000, this Costco also serves the outlying areas (add another 250,000) and some from the bush ship stuff out by plane. They do a lot of durables (furniture, TVs, appliances, etc.) and non-durable sales (food and clothes) - I guess some people think you can never have enough blue tarps!!. In fact, my beautiful bride only allows me to shop there on Fridays because I don't do well in crowded stores
(LOL)... but they also sell beer, wine and other distilled spirits
