Raisins

I am fully and completely addicted to the frosted raisins in Post Raisin Bran.  I'll often buy a whole box, and just pick out all the raisins, and just end up with a box of mostly bran.

Unfortunately, buying individual raisins, boxes, bags, whatever, they're always unfrosted -- just raisins.  Where do I find the good stuff?
