Too bad customers don't have a strong relationship with Kmart.
I'd say it's the other way around. My wife and I always hit the Kansas State Fair in September. It's a good two hour drive for us and it used to have the nearest K-Mart store. A couple of years ago, K-Mart had their Super S oil on sale at that time. I stopped in there to purchase some and it was clearly sale-priced on the shelf, but rang up wrong at the cash register. I mentioned it to the cashier and she had somebody check on the price. The "associate", or whatever K-Mart calls them tells me that it's not on sale. I go back to the automotive section and the associate had pulled the sale price sticker off the shelf.
I was going to grab a flyer and point out that it was clearly on sale, but I just simply gave up and left without making a purchase.
The next year we drove past it, it was boarded up and had weeds growing between the cracks in the parking lot. That's been about my experience with every K-Mart store that I've tried to give business to and that's why their stores are ghost towns.
