Biggest bang for the buck
First I'd like to say, this website/forum is amazing! I spend most of my time here learning and lurking, so I really appreciate the info that is available here.
On to the question:
We are on a pretty tight budget and it's no secret this style of eating is typically not cheap, so what type of food should I spend more $ on to get high quality versus settling for what's available at the standard grocery store? Which is more important? Should we (family of 4) spend more of our budgeted grocery money on high quality meat or free-range eggs or locally grown veggies, etc?
