Don't know about rounds but I get export hay delivered for $6.50 a bail.
my horses LOVE it - it's compressed hay, so takes so used to feeding it - it's easy to over feed.
I'm about to go up to springton to get Hay off my friend (oaten, really fine with HEAPS of heads) but don't know how much yet.
I did once get a round from a guy on One Tree Hill road, but haven't used him in yearrrrs.
