Wasn't there someone who posted in here a long time ago who advertised bulk factory cut foam core cake circles and boards?

Anyone know of a place? Where do you get your ready to use foam core cake circles and boards from?
Or wholesale foam core sheets to cut.

I'm trying to figure out the cost comparison vrs continuing to make them from foam core boards purchased at a local store. So do you guys and gals know of anyplace that is a super deal?

Thanks.
