Source for game pieces

I like to use stackable plastic pieces for some of my prototypes, and people sometimes ask where I get them. Here's a link (you can click on the post title):

As I write, they're $9.50 (plus shipping) for 500 in ten colors.

EAIEducation is also my best source for plastic cubes, two-sided disks, one-inch plastic square counters, and other useful game components, usually in bulk.
