Costco has few items compared to a typical big-box or grocery store. Most of the items are in bulk containers, positioned by fork lift, and cost $10+. They don't bag items after check out. The employees don't dawdle around; they are always hustling. It's hard to get out of Costco without spending $100. They must have a large revenue/employee. They probably have $1k/min flowing out of the store; much more than Walmart. Sams Club is dingy and poorly lit. It's a reflection of Walmart.
