I can't find just a single box of kleenex that the $1.89 fao will cover, however if you buy the 3 pack it does qualify for the 1.89 FAO, and there is a $1 coupons.com available. It would make the 3 pack. I believe the 3 pack was 3.98 or close there. Would be roughly $1.09. Not to bad if you really want the kleenex and purchasing at WM. I will grab it tomorrow and confirm the price.
I found a pack of 2 boxes that was 2.98. I will use them even if they aren't free so I added those to my pick up order. There were not any single boxes listed even showing as out of stock.
Using the Walmart shopping app, I ordered the Kleenex tissue. The store was out and offered me a substitute for the same price.. I received a 4pk for the same price as the 2pk.
