<font color=blue>K-Mart had no consistent strategy. On the one hand they tried to position as a discounter - on the other hand they wanted to go more upmarket </font color=blue>
Part of this is historical. Kmart was the discount division of the S. S. Kresge Company, set up to combat Target and other discounters. Anybody seen any Kresge stores lately? The one in Elkhart, IN, disappeared shortly after the Kmart opened locally - with fewer staff and lower-quality merchandise. The local Target stores have been more up-scale than the local K-Marts for several years. (Is Target still Dayton-Hudson? I ought to look it up).
<font color=blue>Wal-Mart's operations dwarf those of K-Mart.</font color=blue>
Indeed. Notice how much better products scan now than they did ten years ago? Wal-Mart threatened selected suppliers would be sold on consignment, and paid when the product was sold. And if the scanner didn't read the label, the product would just go into the customer's bag . . .
We've now got three Meijer stores in the general area, three (that I know of) Wal-Marts (two 'super', one regular) along with two Sam's Clubs, and two Target stores in operation, and a Super Target in construction. And two K-Marts, althugh I think one of the K-Marts was just renamed a 'Big-K' or some such sillyness.
One of the problems I've had with K-Mart, and the reason I haven't been in one in years, has been their incredibly complex merchandise accounting process for clothing. Scan the price - then tear off the department tag - then press the appropriate department button on the register - then slide the tag into one of a half-dozen or so slots on the front of the register. It's like the scanner isn't hooked up to *anything* and is just pulling a bar-coded price off the label. I switched to Sears and Target for clothing before Wal-Mart or Meijer spread into the area because of this incredible inefficiency.
One of the largest data warehouse operations running is the one Wal-Mart keeps on their products, stores, and customers. They can tell which advertised items sold better because of the ads, what additional items were purchased with the promoted items, and what product mixes work best for each store in the chain. I haven't heard anything about a K-Mart data warehouse.
