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.

Some Sam's clubs are just as nice as Costcos. It really depends on the market it is in. It just seems that Costcos minimum standard is higher. Because there is variation in Costco quality as well... But Costco is more likely to only locate in the more upmarket locations.
