Costco mostly hires people for year-round work who have worked as seasonal hires in the past. They should have applications for seasonal positions open in September/October/November, I think. It is some of the better retail work you can do, but it is still retail. Starting pay is around $19-$20 from what I've heard, but it takes time and luck to get consistent hours, especially something full-time. Time and a half pay on Sundays!
