Bev, check out Joann's online.
Sometimes you can gets TONS of batting for cheap.
I stopped buying batting at the local stores (ok, when I COULD buy at local stores) and started buying batting by the HUGE rolls from Joanns.
Instead of paying something like $8/yard, I would buy in bulk and pay only $4/yard. Then, included I would get FREE shipping, so that was a plus. Just gotta keep looking every week. Last one I bought was for a gift for a friend. Got her the 90 wide by 40 feet for $125.
