Meat and cheese ends at your deli counter
Neighbor lady is super super frugal. She was telling me you could buy the ends of deli meats/cheeses at the deli for a buck a pound. So you're basically saving like 400-500 percent.
I tried it today. I went to Rulli Bros (local mom and pop supermarket) and ordered some ends, and the lady gave me 3 pounds of meat ends and 2 pounds of cheese ends (mostly Swiss). Besides the ends, it also has miscuts. There was salami, prosciutto, ham, peppered roast beef, turkey.
Anyway, it was only $5 for a lot of food. I grabbed some hoagie buns, and we had awesome subs for dinner made of a lot of kinds of meats, swiss, lettuce, Italian dressing. I will definitely be buying more.
