When you compare sales/sq ft, don't mix the apples with the oranges. WM's product mix changes the perspective when you compare them with a Goodyear tire store, for instance. Compare the Goodyear store with a Firestone store if you're looking for who's doing a better job in the $/sf category.

WM's figures are in the mega-big range, sure. 24/7/363 in their Super Centers helps. The sq ft number you found may or may not be for floor space. Also, you don't know if they include the leased spaces or those sales numbers.

Probably more minutiae than anybody gives a rat's ass about, but I was just pointing out that the numbers are always rough. Only the guys reading the P/L know - and usually they're not advertising those numbers.
