I did send them the money! They listed it as free just pay shipping & handling I payed by pay pal It took them 3days after the transaction was completed to send me an e-mail that it was a typo and they wanted a additional 100 dollars. I understand that things happen it may have been a typo but that dose not explain why after they changed the price on the mogul why they changed the price on their ballast to free plus shipping Not to mention apparently I'm not the only one they've done this to apparently they have been having typo's for the last six months
