Snack Wars

These special bags of peanut snacks come in small individual sachets featuring a Star Wars character on the front. I have managed to collect 22 of 24; the two I am missing are Finn and General Grievous. I wonder, should I buy another couple of bags to try and get them? 

I have made the bags into Star Wars bookmarks. Currently, Obi-Wan Kenobi is keeping my place in Anderson Cooper's Dispatches From The Edge.
