Pieces from this large set surface rarely. I surmise that the set wasn't produced for more than perhaps 2-3 seasons, possibly because it didn't sell well. In my many years of collecting I have only seen ~6 differently shaped candy containers, with this listing being the first time I've seen this particular design. Given just how rare these pieces are, the ending price seems low to me.
