Cheaply Supplements

Hi people,
i´ve never heard nothing about Manipulation Pharmacy or Chemist,
so, my question is:
does anyone already bought something from this kind of supplement source ?
I´m asking because here on my country, a “natural” formula manipulated by a chemist cost 1/2 or 1/3 than a Label Product from a Famous brand,
not to mention other benefits…

What country are you in?
