BEWARE - the teaser rate of a $buck or $two to get samples will result in massive credit card charges that your credit card company will not be all that willing to help you with since you did enter your CC number. If your CC was stolen they would take an interest.
If you've been scammed, be sure to mail back their junk (doesn't work anyway) and GET A RECEIPT SIGNATURE or they will claim that you didn't mail it back.
Make no mistake, these are CROOKS and they are very well practiced at RIPPING you off. They will play hardball with you so FIGHT BACK!!!
I filed a FRAUD claim with my State Attorney Generals office, you should too.
