Alert! Klinex Tissue at Costco no longer has BoxTops

The other day, I went to buy a dozen of small Klinex Tissue boxes at Costco. They used to have BoxTops on each boxes, but now it's gone. This was a big disappointment for me. So, I alert all the parents who have been buying small Klinex Tissue boxes at Costco. I don't know if the BoxTops disappeared from the large boxes at Costco yet. Please let me know if any of you know about it.
