For The Philosophy Purity Made Simple, there really is no sustitute.  If price is still a concern, QVC offers it in the 8 oz. size all the way up to 32 oz. super size.  You save the most money on the supersize and you don't have to sacrifice the quality!

Don't know of a drugstore dupe for this brand but I found it for $16 online if that is any consolation. My favorite drugstore brand in general is Neutrogena. They usually have a decent selection between oil and cream based cleansers.  Good luck.

I am afraid there is no dupe.  Try Philosophy's website for specials, or go to Amazon.  They sell prestige cosmetics and I bet you can get it there cheaper.
