My Walmart's were Gerber brand. Sometimes they have the prefolded with the padded center, and sometimes the flat.

My daughter-in-law called me last year when a sale was happening at Walmart and they were clearancing out some prefold diaper--I told her to buy me several pkg. They are upstairs in a box. They are trash as far as I am concerned--they are ripping out at the seam in some I opened to look at and not even washed yet. Was also going to do burp clothes with them--the only way that will work now is to hide that shred ripout place with wide ribbons or pretty fabric. The Birdseye Brand I think is what JoAnn's has and I do like that with a layer of good flannel between the outer and inner pieces.
