I have never seen a K-2006 in Pinch a Penny (and was told they do not carry them) and lately I have not seen K-2005 in the one local to me, only the smaller and less expensive Taylor kits. Also, I have never seen the HTH test kit in a Florida Walmart (and I have checked in various areas of the state when I have gone camping--yes I DO have another passion besides pools and computers!, only AquaChem test strips.) Ordering the K-2006 online might be the best choice!
