where do i find the earlier seasons of this show?

also, how long after an episode airs do you have to wait before it is available on nbc.com to watch?

im so obsessed but cant get my fix!

You have to wait a week. Or you can watch it on Friday or Saturday on the Fine Living Network at 8:00.

I have yet to find out where to see the 1st-6th seasons at.
But I am definitely checking out the ending of the latest episode (fell asleep during weigh in!)
