In the Bay Area, where can I find a selection of prisms to buy?

I'm particularly looking for long or short triangular-ish ones. Awesome if BART accessible but not absolutely required.

If you want to buy that, be sure to search for coupon codes, because there's almost always a free shipping and %10 off code running that you can use at the same time.

The Exploratorium had lots last time I was there. Also the Discovery Channel store sells them.
