I'm sure this topic has been posted before, but I'm looking for tips to stay primal while on a very tight budget. I'm going to grad school next year and never grocery shopped for myself (had a meal plan during undergrad). While I'm excited to be a real person and buy my own food, I am on a very limited budget. I'll be living in an area with and Aldi, a Publix, and a Sweetbay Supermarket within a 30-min walk. I won't have a car so the likelihood of going to the much-further farmer's market is low.

What do you all do when your finances are stretched?
What are some of the cheapest primal foods out there?
