I usually cannot find it except during late summer/early fall(canning season). When it does show up I usually buy most of it to last me through the year.
i just ordered a case of 6 for $30. It was going to be around $12-14 for just one and shipping. so i figured I would get the case of 6 for $30 which was the total including shipping. Non of the stores had any, all said it was seasonal.
