Like most big box stores, Wally World looks at dollars produced for square footage used. While they sell fabric, it takes a large square footage area to merchandise and you also have to have employees to service it, two huge negatives from a profit standpoint. It's strictly a dollars and cents thing for them. They don't really care about servicing the customers needs, just how much money an area can produce is their focus. With party supplies, all they need is someone to stock the shelves.
Walmart has forgotten what it takes. I hate to shop there, they are so un- responsive to customer needs. In our small town, you are almost forced to shop there because that's all there is. I hate having to purchase what they have on the shelf and not being able to purchase what I really want. It's a Catch 22, I can drive 60 or so miles to the big city and get what I want, but then I have to fill up the Jeep and spend 3 hours on the road. Sam Walton would turn over in his grave if he could see what his company is doing to it's customers. If there is any alternative, I use it even if I have to pay more.
