I appreciated this post by Penniless Parenting:
“Most people have all these misconceptions about what kinds of meals are cheapest and what kind are not, and I’ve discovered sometimes that what people thought was cheap wasn’t actually that cheap, and what people thought was expensive wasn’t actually expensive, either.”
I’m not sure where Penny lives. She mentions that eggs are .25 a piece. Here, I can get a dozen for .69.
The point of the article being, instead of automatically assuming which foods are inexpensive, we need to research our local market and know prices.
She also links to another post she did with detailed information on whether bone-in or boneless meat is a better deal. Check it out.
