My wedding was 12/8/08, and it webcast was $75 in addition to a package or $375 by itself. I am unsure if he has went up in price, and now he has packages with Randy Chapman as well.
It does say on his website something about the cost of it being very reasonable, so I'm hoping te price would still be around that level. I'm not sure whether we need to do it yet or not to be honest, but it's good to know, thanks!
