I tend to shop at various stores, because I've noticed that certain stores always have things marked down, or always seem to have good deals on certain things (dairy, meat, produce). I've found this to be true in the last three cities that we've lived in. In Fort Worth, Sack and Save almost always has great deals on produce. I always check Kroger's ad vs. Sack and Save's ad. Save a lot is my staple store. If I can't find it on sale at Kroger or Sack and Save, I get it at Save a lot.
I found half gallons of milk at Save a lot for 50 cents. They were on their expiration date. I bought all nine that they had and froze them. We didn't buy milk for several months. Gallons of milk are on sale at Kroger right now for $3 a gallon. Savings: $18
I found butter at Sack and Save for 98 cents. I froze a bunch of them. Nothing wrong with them. Just a loss leader. I bought a lot....maybe 10? I usually spend $2 on butter at Sack and Save. Savings: $10
