Sorry KimmyKim - the ad on the html page is written improperly, it says it will bill to your phone line but in fact it cannot. I called the number and it's from Pilgrim Communications and it offers payment by check, credit card, prepayment - or you can press a number to hear their 1-900 number that you can call to bill to your phone line.
Looks like their webmaster mistakenly used copy for marketing a 1-900 number.
So, at least this line won't charge you if you call. I think that the idea of an 800 number billing your line is an urban myth.
Sincerely,
Brad
