different walmarts carry different bom block kits- would need to know which one you are trying to locate- the local walmart had 5 or 6 different boms' here last year...sometimes with a block or two available---sometimes with more- never with all of the quilt---
someone gave me 4 bom kits they had picked up that they could never find more of so gave up- i just made the blocks into a table runner and called it good-
but if you let us know which bom you are trying to find- and which blocks you have someone here may have others to go with it.
