LOL! ThinkDiesel.
Steve, you haven't ever done business with Wal-Mart/Sam's Wholesale Club. There are so many criteria involved with them, it is almost not worth your while. If you want to make no profit, and wear out your equipment, then a partnership with them is what you need.
People talk about Bill Gates and Microsoft, well, in Arkansas, Wal-Mart and Tyson rule.
One time my Father's pilot had to make an emergency landing at one of Wal-Mart's airports. To make a long story short, they wouldn't give his plane clearance for takeoff until Dad bought fuel from their pumps, when they didn't need fuel. Once they knew who's plane it was they acted like it was a mistake.
