| It looks like Sam's Club dominates in Oklahoma. The very first Sam's Club opened in Midwest City, Oklahoma in 1983. There are now eight Sam's Clubs in Oklahoma. This probably explains why there currently aren't any Costcos in Oklahoma. Overall, there are 602 Sam's Clubs in 48 states (only states that don't have a Sam's Club are Oregon and Vermont). There are 583 Costcos in 40 states. Costco's sales are slightly higher than Sam's Club's, though. |
