Slowcookers are MAJOR grocery budget savers! (Plus they help cut your electric bills!
I always buy whatever meat is on sale and freeze it. Then I have a month or so of meat for really cheap. (In our area, Kroger is best.
Walmart is worst for sales on meat).
For example, recently for $75 I bought:
Butterball Turkey (~ 9 lbs)
Bone-in Honey Ham (I think ~9 lbs)
Two Racks of Ribs
3 Packs of chicken tenders
1 Pack of chicken breasts
Pork tenderloin
2- 5lb Rolls of lean ground beef
I also coupon and stockpile my matchups. I buy what I believe we can eat before it expires.
For example:
When pasta went on sale I bought 10 boxes.
Ragu went on sale a few weeks later and I bought 4 jars (only had two coupons or would have bought more).
This works for household items, too! I love getting free toothpaste, shampoo, Tylenol, etc. at Walgreens every Sunday through couponing.
