I found them at Home Depot in Sioux Falls for 4.95/144 count box. Their on-line inventory said they had 8 boxes and I went there fixing to buy 2 or 3 boxes. Even had the aisle and bay number. Got there said "where do I find aisle E6 bay 5? The guy showed me and they had one lonely box on hand. Bought it and came back home, rechecked online and now the inventory showed 7? The guy that helped was very accomodating, we had looked high and low for more but there were none to be found. Anyway I only use about 1/3 of a square to get my chunk wood started so 144 should last a while.
