I remember when, as a child, I was quite upset when the S&H Green Stamp folks introduced larger ten and fifty-stamp "denominations". Instead of having to lick fifty single stamps to fill a page in a stamp book, five 10s or a single 50 did the same thing. I guess that was good for adults who didn't want to lick hundreds of stamps, but it sucked for us kids who did want to lick 'em.
