Don't get taken by these scammers. I purchased a "FREE Sample" of Viralis Rx, distributed by Vital Surge, Inc., for the $4.95 shipping charge. Surprise, surprise, surprise! I was slow in checking my receipts against my next two statements and when I did I found they had charged my card an extra $89.95 and a $94.90 for another bottle.
I am very careful and usually go so far as to use a "virtual account number" with a limit when making online purchases. but didn't on this one because they were so slick. The bank card company (Chase) refused to reverse the charges until I returned the Viralis.
I couldn't return it because I had taken it and it was absolutely useless. What a Ripoff!.
