Hortica said: I can't say anything about your locale, but here in the SFBA there is a nearby kiln than makes perlite; they only sell it it 2 cu.ft. bags (which are huge, much bigger than a garbage bag) for about $32.
If you have to buy the same bag retail it is closer to $50.
Stores that supply pot growers are often a good source for materials like this.

I did find a pot grower's website, and they have gallon bags of large perlite for $5, which compared to other prices i'm finding seems like a good deal. The same amount on another site is $20. So thanks for that suggestion.
