This is merely one example of the great bargains to be had this time of the year for Halloween collectors. (Although a great time to buy, it is a horrific time to sell, since the recently passed holiday seems to have sated collectors' appetites, a phenomenon that occurs regularly from about early November through late March.) My advice, unless you have to sell, just wait until early April to begin selling anything noteworthy.
