I used to mark mine up and sell them at a profit, as a kid. Easier said than done, but at least 1 house in 10 would go for it. If they wouldn't go for the "retail" price, I was "authorized" to offer it at a "discount" on a limited basis.
I also used to pay neighborhood kids 10 cents commision on any candy bar they sold for me (they were not allowed to offer the candy at a "discount"). I never really made any real money at it, but it was a nice way to hedge my efforts against the stereo they always promised the best seller.
By Junior High school, I was out of the fundraising business and went right into blackmarket candy distribution on campus. By the end of my 8th grade year, I had 3 kids buying from me as a wholesaler. Apparently, I was the only one in the school who knew about buying candy in bulk at the grocery store.
My blackmarket in-class candy business was funny enough to deserve a new thread devoted to it.
