too right. you need a chemist's shop. then it is really cheap.

there are mail orders shops too of this kind if you find none.

and the other option is pool supplys.
you can get H2O2 at pool supplys.

it is aound 20% and used in the oxygen-based systems.

i forgot the name, it is only a german name and may not be helpful to you 
anyway...
i can search it if you need.
