You should never trust a site just because it claims to be secure. You should do your homework on the company to ensure that it is legitimate. Try to obtain a physical address rather than merely a post office box and a phone number.

For further reassurance, call the seller to see if the number is correct and valid. Send them an e-mail to see if they have an active e-mail address and be wary of sellers who use free web-based e-mail accounts.

Be cautious when responding to special offers, especially through unsolicited e-mail. If a deal is too good to be true, it probably is. Don’t be conned by such scams.
