    STOP the damned jumping around of all of the junk ads on your website. very distracting to try to read a bullet note and the sentence jumps out of sight, then down 4 inches, then compressed into 8 bullets, then back and starts again. It is not in your best interest. there are lots of readable sites out there, and yours is definitely not one.

    Number 10 in your pro list states “vitamin BB” which number was supposed to be in place of that second “B”?
