one of our lqs carry them-- they are $3.39 apiece and very nice towels.
some quilt shops do carry them- usually the shops that tend to specialize in reproduction type fabrics/thimbleberries
i (think) the towels here are from marcus brothers- but i might be mistaken.
go down the list of shops on the 'fabshophop' you are bound to find a dozen or so shops that carry them.
