I have purchased Food grade hydrogen perioxide at a health food store in
St.Paul, MN. I spilled some on my work table and it ate a hole in it.  I
beleive I paid aroun $10 for a quart.  You don't need the pharmasitical
or chemicaly pure grade that you can get from a pharmacy or scientific
supply house.
