Holy arceus they're expensive. D;
I guess I won't be buying any, unless I manage to find some offline. I find Pokemon stuff in thrift stores (haha at least it's cheap) and quirky little stores that sell old stuff.
People are selling these marbles for $2 each...a Charmander one if $7.50. >_>
nib proably.
Mixed lots would be cheaper. Not mint but still in good condition. I've found a mixed lot, 91 in total, with a starting bid of $10. 4 days till it ends but still.
