Yeah its another case of "read the fine print". I'm always weary of things on TV in the first place... but yeah, and how could they charge you without your knowledge... I know I check my bank funds on a daily basis and the second I notice a debit that I did not authorize I call my bank and they take care of it, within reason.

That happened to me at Best Buy once, you know when you check out and they ask you about magazine subscriptions and you have to "agree" to the terms? Well in THAT fine print it also says they will charge you X dollars after Y days monthly using the credit card you used to make your purchase. Well of course I didn't read it, it was on the debit card screen and so small and.. well hard to read in the first place, plus they don't give you any papers they just print somethin on your receipt... well six months later come to find a bunch of charges being automatically debited from my account... call up my bank, said I did not authorize this nor was I made aware at the time that it would be an automatic montly deduction and they filed a complaint with the company and credited my account back with the funds that were taken out

So since then I am very aware of reading fine prints and declining ALL "free" offers, cause most times they aren't even free.

If it's "too good to be true", then it probably is.
