If you were referencing my post, then i think you misunderstood what I meant by buying in bulk. I don't shop at Costco, so I absolutely didn't mean shopping at Costco.You mentioned it in your last sentence, but it needs to be reiterated. When you don't have enough money from paycheck to paycheck to pay rent, pay utilities and buy the most basic of foods, you aren't buying in bulk. These aren't Costco shoppers (who are typically mid-to-upper class).
I was referring only to small deals my local stores offer. One can of beans is $1, but they often have small deals on 5 cans of beans. Chicken parts are $5 per pound, but a whole chicken is $3 per pound, and the family 5pound pack of chicken is often on sale for $2 per pound.
To me, 3 pounds of meat = buying in bulk, because I can make 3 pounds last over a week. I cook up the 3 pounds, then spilt it up into portions to last however long I need that meat to last to my next paycheck.
Every day, I do something different with it, if possible. Like spices or honey or mixing it with other leftovers.
