I wouldnt ever buy something that is such an obvious scam, but my wife, she buys all kinds of things on the internet/infomercials. What I did is got a paypal account and get a free service that can issue me a one time use number to use on things that we feel could be suspicious. Magazines, overseas orders, anything that isnt a local big name company. I think I get the one time use numbers cause I go thru a lot of money on paypal? but look into if your bank might have the same thing? It worked out great for me, several times we have ordered something, get billed once and then couple weeks later they try to charge me again or some other company tries to put a charge thru, I get asked if I accept this charge from Paypal and I say no. NO MUSS NO FUSS
In the last few months paypal has tightened their belts alitle so not sure if they still do it? but it seems like other banks would?
