ISO this particular pillow case Target brand GRAY

Been searching for this pillow case and cannot find it ANYWHERE... All Target stores everywhere seem to be sold out of this particular item, for some reason, and I can't find it on any other selling websites.... I grabbed one in the store a while back thinking it was a 2-pack but it actually just came with one.... been trying to hunt down just ONE more, I'm hoping somebody on here would be able to help connect me to one or would have an extra I may buy.... last picture is just to show packaging.
