I eat a lot of meat so when I find it on sale I buy it and freeze it. I also buy frozen veggies on sale and freeze them. I love fresh veggies but I only buy what I will eat that week.
I too pay cash at the grocery store.
I make all my food from scratch and that saves me a lot of money.
I plan my expenses each week and that helps a lot. I always put aside a little fun money but if I don't spend it then I am ahead of the game the next week.
Happy savings friends!
