Blackmores is even cheaper in Coles. I get mine for $17.95. (they have a bigger buying power). At the moment though you can get 100 tablets for $22.00 in Coles this week :-)

I use blackmores cause with Laz studying naturopathy he did an analysis of all the brands and Blackmores came up as the best (and it was an added bonus that it was not too expensive)
