I've done absolutely zero research on this idea, but I'm thinking it could be a winning business concept.  Find items that come in variety packs, say Tootsie Pops, and buy a bunch and package all of the same kind together and each kind separately.  Personally I much prefer the red Tootsie Pops over the others so I'd love to be able to buy a box full of just red Tootsie Pops.  If the Tootsie Pops folks don't go for that idea how about letting me buy boxes, pull out all the brown ones, and sell brown-less boxes?

This same concept could work with other confections as well.  Jelly beans? You bet.  I'm one of four people in the US who likes black jelly beans and so every Easter my family is on the lookout for bags of black jelly beans.  They used to be easy to find, now not-so-much.

Now you can't say I've never given you anything.
