It is my understanding that mfg companies will make cheaper fabric in the same line for sale in certain stores. I often wondered why when I went to one store and the fabric was fabulous, but at another store, it was lousy. I think what may be happening is that fabric is getting very costly to buy, so the mfg might be making fabric with lesser thread count so that they can sell if for less. The cotton crop has not done well these past few years which is pushing cotton costs up.
