You can tell this scam cos they always come in the form of blogs with the same comments and same content just different author pic and bio. Hacked one of these blogs recently and was able to glean some information about what this scam is.

If you give them your credit card you cancel the card don’t just block the transactions.

Hello Brytnee. Unfortunately i did the same. I called and called and could not get a hold of anyone, i ended up and called my bank to dispute the charge, i have chase bank. The following day, and the next day after that i received two more charges on my Atm/Credit card, i had to dispute all three charges and i am thankful my bank reimbursed my money. First they said that the kit was $1.97 and charged me $2.97 than there was a charge for $74.97 than another charge the following day for $19.95. Who knows what would have happened if i didn’t cancel my card and have my bank issue me a new one. Around that time i found an email address and they emailed me back saying that this is not a scam and that a lot of people make seriously good money with this program, i emailed them back and had some choice words for them, also to let them know that i reported them to the better business bureau, consumer affairs, and rip off report. My advice to you is, if you don’t mind canceling your credit card, i would do it immediately, like i said they charged me three consecutive days for a total of $97.89 and they are probably going to do the same to you, they just pass on your credit card information to the next person, they have no conscious. I also see how they might work out of the uk, so it would be harder for them to get caught. I hope this helps, unfortunately we fell for the same garbage. Edward.
