What are you ladies doing for favors? I already bought these "chair" favor boxes that double as place cards, but I'm not sure what to put in them. I was thinking Hershey kisses (because they're silver), but they are EXPENSIVE for the amount I would need to fill 100 2x2" boxes. I'm not sure what to do.

If I suck it up and buy the kisses, when should I load them in? I don't want to wait until the last minute, but I also don't want to have them melt and mess up the boxes over the summer. What to do... what to do?
What are your favors?
