I've started shopping at the spud shed for most things (veg, fruits, meat & some other bits) after reading this blog post, http://www.spru.ce.id.au/?p=137.
So far I've brought the bill down from about $200-$230 pw (for two adults who entertain a bit) down to $180 and hope to bring it down further this week with a bit of planing
I'm hoping this will set us up in good habits for when we do have a baby and I'm on maternity leave
