If you're looking for Series 1 chargers past #1-5, it's worth trying Amazon. I was able to find most of the Series 1 charger packs that I was missing (gray chargers w/foil stickers and the "fossil" variants packed in)--though shipping might take a while, I ordered them a week and a half ago and they just shipped yesterday.

Between that and the Pteranodon (#6) set I found in Walmart over the weekend, all I'm missing from Series 1 are the Pachycephalosaur (#8) and Archelon (#21) sets...and nobody seems to have those, not even on eBay.
