Interesting....

Anyway, I just paid $11.60 (plus shipping) for 8lbs of Sodium Carbonate at the Chemisty Store http://www.chemistrystore.com/ Arm and Hammer might be cheaper due to the shipping and handling I paid (a little less than 19 bucks, but then I did buy 10lbs of sulfite as well).

Oh, well.

BTW, don't worry about the off topic thing. Converstations go off topic in the real world, don't they?
